So I had read through most of this before I realized what it was you were reporting. As far as the behavior there are a few things going on. I have some additional comments below but they are mostly based on what I had read up to that point. As far as possible issues for item 1. The VLAN adds 4 bytes of data of the payload, when it is stripped it can result in a packet that is 56 bytes. These missing 8 bytes can cause issues as it forces the CPU to do a read/modify/write every time the device writes to the 64B cache line instead of just doing it as a single write. This can be very expensive and hurt performance. In addition it adds 4 bytes on the wire, so if you are sending the same 64B packets over the VLAN interface it is bumping them up to 68B to make room for the VLAN tag. I am suspecting you are encountering one of these type of issues. You might try tweaking the packet sizes in increments of 4 to see if there is a sweet spot that you might be falling out of or into. Item 2 is a known issue with the NICs supported by ixgbe, at least for anything 82599 and later. The issue here is that there isn't really an Rx descriptor cache so to try and optimize performance the hardware will try to write back as many descriptors it has ready for the ring requesting writeback. The problem is as you add more rings it means the writes get smaller as they are triggering more often. So what you end up seeing is that for each additional ring you add the performance starts dropping as soon as the rings are no longer being fully saturated. You can tell this has happened when the CPUs in use suddenly all stop reporting 100% softirq use. So for example to perform at line rate with 64B packets you would need something like XDP and to keep the ring count small, like maybe 2 rings. Any more than that and the performance will start to drop as you hit PCIe bottlenecks. > This is not only problem/bug report - but some kind of comparision plus > some toughts about possible problems :) > And can help somebody when searching the net for possible expectations :) > Also - dono better list where are the smartest people that know what is > going in kernel with networking :) > > Next time i will place summary on top - sorry :) > >> >>> Tested HW (FORWARDING HOST): >>> >>> Intel(R) Xeon(R) Gold 6132 CPU @ 2.60GHz >> >> Interesting, I've not heard about a Intel CPU called "Gold" before now, >> but it does exist: >> >> https://ark.intel.com/products/123541/Intel-Xeon-Gold-6132-Processor-19_25M-Cache-2_60-GHz >> >> >>> Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) >> >> This is one of my all time favorite NICs! > > Yes this is a good NIC - will have connectx-4 2x100G by monday so will also > do some tests > >> >>> >>> Test diagram: >>> >>> >>> TRAFFIC GENERATOR (ethX) -> (enp216s0f0 - RX Traffic) FORWARDING HOST >>> (enp216s0f1(vlan1000) - TX Traffic) -> (ethY) SINK >>> >>> Forwarder traffic: UDP random ports from 9 to 19 with random hosts from >>> 172.16.0.1 to 172.16.0.255 >>> >>> TRAFFIC GENERATOR TX is stable 9.9Mpps (in kernel pktgen) >> >> What kind of traffic flow?

Generally less is more. When I perform tests I will usually drop the ring size for Tx to 128 and Rx to 256. That reduces the descriptor caches per ring to 1 page each for the Tx and Rx. With an increased interrupt rate you should be able to service this optimally without too much issue. Also for these type of tests the Tx ring never really gets over 64 packets anyway since a single Tx ring is always populated by a single Rx ring so as long as there isn't any flow control in play the Tx queue should always be empty when the Rx clean-up begins and it will only be populated with up to NAPI poll weight worth of packets. > Can be a little better performance for smaller frames like 64 - with rx ring > set to 1024 > below 1 core/1 RSS queue with rx ring set to 1024 > > 0;1;64;1530112;91772160;1529919;88724208 > 1;1;64;1531584;91872000;1531520;88813196 > 2;1;64;1531392;91895040;1531262;88831930 > 3;1;64;1530880;91875840;1531201;88783558 > 4;1;64;1530688;91829760;1530688;88768826 > 5;1;64;1530432;91810560;1530624;88764940 > 6;1;64;1530880;91868160;1530878;88787328 > 7;1;64;1530496;91845120;1530560;88765114 > 8;1;64;1530496;91837440;1530687;88772538 > 9;1;64;1530176;91795200;1530496;88735360 > > so from 1.47Mpps to 1.53Mpps > > But with bigger packets > 200 performance is better when rx is set to 4096 This is likely due to the interrupt moderation on the adapter. Instead of adjusting the ring size up you might try pushing the time between interrupts down. I have generally found around 25 usecs is best. You can change the rx-usecs value via ethtool -C to get the rate you want. You should find that it will perform better that way since you put less stress on the CPU caches. > >> >>> ip link set $i txqueuelen 1000 >> >> Setting tx queue len to the default 1000 seems redundant. > > Yes cause i'm changing this parameter also to see if any impact on > performance we have >> >> >>> ethtool -C $i rx-usecs 10 >> >> Adjusting this also have effects you might not realize.

The logic for trying to find an ideal interrupt rate for these kind of tests is actually pretty simple. What you want to do is have the updates coming fast enough that you never hit the point of descriptor starvation, but at the same time you don't want them coming too quickly otherwise you limit how many descriptors can be coalesced into a single PCI DMA write since the descriptors have to be flushed when an interrupt is triggered. > Same test as above with rx ring 1024 tx ring 1024 and rxusecs set to 256 > (1Core/1RSS queue): > 0;1;64;1506304;90424320;1506626;87402868 > 1;1;64;1505536;90343680;1504830;87321088 > 2;1;64;1506880;90416640;1507522;87388120 > 3;1;64;1511040;90700800;1511682;87684864 > 4;1;64;1511040;90681600;1511102;87662476 > 5;1;64;1511488;90712320;1511614;87673728 > 6;1;64;1511296;90700800;1511038;87669900 > 7;1;64;1513344;90773760;1513280;87751680 > 8;1;64;1513536;90850560;1513470;87807360 > 9;1;64;1512128;90696960;1512000;87696000 > > And rx-usecs set to 1 > 0;1;64;1533632;92037120;1533504;88954368 > 1;1;64;1533632;92006400;1533570;88943348 > 2;1;64;1533504;91994880;1533504;88931980 > 3;1;64;1532864;91979520;1532674;88902516 > 4;1;64;1533952;92044800;1534080;88961792 > 5;1;64;1533888;92048640;1534270;88969100 > 6;1;64;1533952;92037120;1534082;88969216 > 7;1;64;1533952;92021760;1534208;88969332 > 8;1;64;1533056;91983360;1532930;88883724 > 9;1;64;1533760;92021760;1533886;88946828 > > rx-useck set to 2 > 0;1;64;1522432;91334400;1522304;88301056 > 1;1;64;1521920;91330560;1522496;88286208 > 2;1;64;1522496;91322880;1522432;88304768 > 3;1;64;1523456;91422720;1523649;88382762 > 4;1;64;1527680;91676160;1527424;88601728 > 5;1;64;1527104;91626240;1526912;88572032 > 6;1;64;1527424;91641600;1527424;88590592 > 7;1;64;1526336;91572480;1526912;88523776 > 8;1;64;1527040;91637760;1526912;88579456 > 9;1;64;1527040;91595520;1526784;88553472 > > rx-usecs set to 3 > 0;1;64;1526272;91549440;1526592;88527488 > 1;1;64;1526528;91560960;1526272;88516352 > 2;1;64;1525952;91580160;1525888;88527488 > 3;1;64;1525504;91511040;1524864;88456960 > 4;1;64;1526272;91568640;1526208;88494080 > 5;1;64;1525568;91545600;1525312;88494080 > 6;1;64;1526144;91584000;1526080;88512640 > 7;1;64;1525376;91530240;1525376;88482944 > 8;1;64;1526784;91607040;1526592;88549760 > 9;1;64;1526208;91560960;1526528;88512640 > > >> >>> ethtool -L $i combined 16 >>> ethtool -K $i gro on tso on gso off sg on l2-fwd-offload off >>> tx-nocache-copy on ntuple on >> >> Here are many setting above. > > Yes mostly NIC defaults besides the ntuple that is on (for testing some nfc > drop filters - and trying to test also tc-offload ) > >> GRO/GSO/TSO for _forwarding_ is actually bad... in my tests, enabling >> this result in approx 10% slowdown. > > Ok lets give a try :) > gro off tso off gso off sg on l2-fwd-offload off tx-nocache-copy on ntuple > on > rx-usecs 10 > 1 CPU / 1 RSS QUEUE > > 0;1;64;1609344;96537600;1609279;93327104 > 1;1;64;1608320;96514560;1608256;93293812 > 2;1;64;1608000;96487680;1608125;93267770 > 3;1;64;1608320;96522240;1608576;93297524 > 4;1;64;1605888;96387840;1606211;93148986 > 5;1;64;1601472;96072960;1601600;92870644 > 6;1;64;1602624;96180480;1602243;92959674 > 7;1;64;1601728;96107520;1602113;92907764 > 8;1;64;1602176;96122880;1602176;92933806 > 9;1;64;1603904;96253440;1603777;93045208 > > A little better performance 1.6Mpps > But wondering if disabling tso will have no performance impact for tcp > traffic ...

The default hash will only has on IPv4 addresses. Enabling the use of UDP ports would allow for more entropy.

What is the rate difference? Also did you account for the header size when noticing that there is a difference in rates? I just want to make sure we aren't seen an issue where you are expecting a rate of 14.88Mpps when VLAN tags drop the rate due to header overhead down to something like 14.2Mpps if I recall correctly. > >> >>> >>> settings below: >>> >>> ethtool -k enp216s0f0 >>> Features for enp216s0f0: >>> Cannot get device udp-fragmentation-offload settings: Operation not >>> supported >>> rx-checksumming: on >>> tx-checksumming: on >>> tx-checksum-ipv4: off [fixed] >>> tx-checksum-ip-generic: on >>> tx-checksum-ipv6: off [fixed] >>> tx-checksum-fcoe-crc: off [fixed] >>> tx-checksum-sctp: on >>> scatter-gather: on >>> tx-scatter-gather: on >>> tx-scatter-gather-fraglist: off [fixed] >>> tcp-segmentation-offload: on >>> tx-tcp-segmentation: on >>> tx-tcp-ecn-segmentation: off [fixed] >>> tx-tcp-mangleid-segmentation: on >>> tx-tcp6-segmentation: on >>> udp-fragmentation-offload: off >>> generic-segmentation-offload: off >>> generic-receive-offload: on >>> large-receive-offload: off >>> rx-vlan-offload: on >>> tx-vlan-offload: on >>> ntuple-filters: on >>> receive-hashing: on >>> highdma: on [fixed] >>> rx-vlan-filter: on >>> vlan-challenged: off [fixed] >>> tx-lockless: off [fixed] >>> netns-local: off [fixed] >>> tx-gso-robust: off [fixed] >>> tx-fcoe-segmentation: off [fixed] >>> tx-gre-segmentation: on >>> tx-gre-csum-segmentation: on >>> tx-ipxip4-segmentation: on >>> tx-ipxip6-segmentation: on >>> tx-udp_tnl-segmentation: on >>> tx-udp_tnl-csum-segmentation: on >>> tx-gso-partial: on >>> tx-sctp-segmentation: off [fixed] >>> tx-esp-segmentation: off [fixed] >>> fcoe-mtu: off [fixed] >>> tx-nocache-copy: on >>> loopback: off [fixed] >>> rx-fcs: off [fixed] >>> rx-all: off >>> tx-vlan-stag-hw-insert: off [fixed] >>> rx-vlan-stag-hw-parse: off [fixed] >>> rx-vlan-stag-filter: off [fixed] >>> l2-fwd-offload: off >>> hw-tc-offload: off >>> esp-hw-offload: off [fixed] >>> esp-tx-csum-hw-offload: off [fixed] >>> rx-udp_tunnel-port-offload: on >>> >>> >>> Another thing is that forwarding performance does not scale with number >>> of cores when 7+ cores are reached >> >> I've seen problems with using Hyper-Threading CPUs.

One thing you might look at doing is CPU pinning the interrupts for the NIC in a 1:1 fashion so that the queues are all bound to separate cores without them sharing between Hyper-threads. > Turbostats can help here: > Package Core CPU Avg_MHz Busy% Bzy_MHz TSC_MHz IRQ SMI C1 > C2 C1% C2% CPU%c1 CPU%c6 CoreTmp PkgTmp PkgWatt RAMWatt > PKG_% RAM_% > - - - 72 2.27 3188 2600 194844 0 64 > 69282 0.07 97.83 18.38 79.36 -4 54 123.49 16.08 0.00 > 0.00 > 0 0 0 8 0.74 1028 2600 1513 0 32 > 1462 1.50 97.99 10.92 88.34 47 51 58.34 5.34 0.00 > 0.00 > 0 0 28 7 0.67 1015 2600 1255 0 12 > 1249 0.96 98.61 10.99 > 0 1 1 7 0.68 1019 2600 1260 0 0 > 1260 0.00 99.54 8.44 90.88 49 > 0 1 29 9 0.71 1208 2600 1252 0 0 > 1253 0.00 99.48 8.41 > 0 2 2 7 0.67 1019 2600 1261 0 0 > 1260 0.00 99.54 8.44 90.89 48 > 0 2 30 7 0.67 1017 2600 1255 0 0 > 1255 0.00 99.55 8.44 > 0 3 3 7 0.68 1019 2600 1260 0 0 > 1259 0.00 99.53 8.46 90.86 -4 > 0 3 31 7 0.67 1017 2600 1256 0 0 > 1256 0.00 99.55 8.46 > 0 4 4 7 0.67 1027 2600 1260 0 0 > 1260 0.00 99.54 8.43 90.90 -4 > 0 4 32 7 0.66 1018 2600 1255 0 0 > 1255 0.00 99.55 8.44 > 0 5 5 7 0.68 1020 2600 1260 0 0 > 1257 0.00 99.54 8.44 90.89 50 > 0 5 33 7 0.68 1019 2600 1255 0 0 > 1255 0.00 99.55 8.43 > 0 6 6 7 0.70 1019 2600 1260 0 0 > 1259 0.00 99.53 8.43 90.87 -4 > 0 6 34 7 0.70 1019 2600 1255 0 0 > 1255 0.00 99.54 8.43 > 0 8 7 7 0.68 1019 2600 1262 0 0 > 1261 0.00 99.52 8.42 90.90 50 > 0 8 35 7 0.67 1019 2600 1255 0 0 > 1255 0.00 99.55 8.43 > 0 9 8 7 0.68 1019 2600 1260 0 0 > 1257 0.00 99.54 8.40 90.92 49 > 0 9 36 7 0.66 1017 2600 1255 0 0 > 1255 0.00 99.55 8.41 > 0 10 9 7 0.66 1018 2600 1257 0 0 > 1257 0.00 99.54 8.40 90.94 -4 > 0 10 37 7 0.66 1018 2600 1255 0 0 > 1255 0.00 99.55 8.41 > 0 11 10 7 0.66 1019 2600 1257 0 0 > 1259 0.00 99.54 8.56 90.77 -4 > 0 11 38 7 0.66 1018 2600 1255 0 3 > 1252 0.19 99.36 8.57 > 0 12 11 7 0.67 1019 2600 1260 0 0 > 1260 0.00 99.54 8.44 90.88 -4 > 0 12 39 7 0.67 1019 2600 1255 0 0 > 1256 0.00 99.55 8.44 > 0 13 12 7 0.68 1019 2600 1257 0 4 > 1254 0.32 99.22 8.67 90.65 -4 > 0 13 40 7 0.69 1019 2600 1256 0 4 > 1253 0.24 99.31 8.66 > 0 14 13 7 0.71 1020 2600 1260 0 0 > 1259 0.00 99.53 8.41 90.88 -4 > 0 14 41 7 0.72 1020 2600 1255 0 0 > 1255 0.00 99.54 8.40 > 1 0 14 3564 99.19 3594 2600 125472 0 0 > 0 0.00 0.00 0.81 0.00 54 54 65.15 10.74 0.00 > 0.00 > 1 0 42 3 0.07 3701 2600 1255 0 0 > 1255 0.00 99.95 99.93 > 1 1 15 11 0.32 3301 2600 1257 0 0 > 1257 0.00 99.81 26.37 73.31 42 > 1 1 43 10 0.31 3301 2600 1255 0 0 > 1255 0.00 99.82 26.38 > 1 2 16 10 0.31 3301 2600 1257 0 0 > 1257 0.00 99.81 26.37 73.32 39 > 1 2 44 10 0.32 3301 2600 1255 0 0 > 1255 0.00 99.82 26.36 > 1 3 17 10 0.32 3301 2600 1257 0 0 > 1257 0.00 99.81 26.40 73.28 39 > 1 3 45 11 0.32 3301 2600 1255 0 0 > 1255 0.00 99.81 26.40 > 1 4 18 10 0.32 3301 2600 1257 0 0 > 1257 0.00 99.82 26.40 73.28 40 > 1 4 46 11 0.32 3301 2600 1255 0 0 > 1255 0.00 99.82 26.40 > 1 5 19 11 0.33 3301 2600 1257 0 0 > 1257 0.00 99.81 26.40 73.27 39 > 1 5 47 11 0.33 3300 2600 1255 0 0 > 1255 0.00 99.82 26.40 > 1 6 20 12 0.35 3301 2600 1257 0 0 > 1257 0.00 99.81 26.38 73.27 42 > 1 6 48 12 0.36 3301 2600 1255 0 0 > 1255 0.00 99.81 26.37 > 1 8 21 11 0.33 3301 2600 1257 0 0 > 1257 0.00 99.82 26.37 73.29 42 > 1 8 49 11 0.33 3301 2600 1255 0 0 > 1255 0.00 99.82 26.38 > 1 9 22 10 0.32 3300 2600 1257 0 0 > 1257 0.00 99.82 26.35 73.34 41 > 1 9 50 10 0.30 3301 2600 1255 0 0 > 1255 0.00 99.82 26.36 > 1 10 23 10 0.31 3301 2600 1257 0 0 > 1257 0.00 99.82 26.37 73.33 41 > 1 10 51 10 0.31 3301 2600 1255 0 0 > 1255 0.00 99.82 26.36 > 1 11 24 10 0.32 3301 2600 1257 0 0 > 1257 0.00 99.81 26.62 73.06 41 > 1 11 52 10 0.32 3301 2600 1255 0 4 > 1251 0.32 99.50 26.62 > 1 12 25 11 0.33 3301 2600 1257 0 0 > 1257 0.00 99.81 26.39 73.28 41 > 1 12 53 11 0.33 3301 2600 1258 0 0 > 1254 0.00 99.82 26.38 > 1 13 26 12 0.36 3317 2600 1259 0 0 > 1258 0.00 99.79 26.41 73.23 39 > 1 13 54 11 0.34 3301 2600 1255 0 0 > 1254 0.00 99.82 26.42 > 1 14 27 12 0.36 3301 2600 1257 0 5 > 1251 0.24 99.58 26.54 73.10 41 > 1 14 55 12 0.36 3300 2600 1255 0 0 > 1254 0.00 99.82 26.54 > > > So it looks like in all tests i'm using core+sibling > But side effect of this is that : > 33 * 100.0 = 3300.0 MHz max turbo 28 active cores > 33 * 100.0 = 3300.0 MHz max turbo 24 active cores > 33 * 100.0 = 3300.0 MHz max turbo 20 active cores > 33 * 100.0 = 3300.0 MHz max turbo 14 active cores > 34 * 100.0 = 3400.0 MHz max turbo 12 active cores > 34 * 100.0 = 3400.0 MHz max turbo 8 active cores > 35 * 100.0 = 3500.0 MHz max turbo 4 active cores > 37 * 100.0 = 3700.0 MHz max turbo 2 active cores > > So more cores = less MHz per core/sibling Yes that is always a trade off. Also the ixgbe is limited in terms of PCIe bus bandwidth. The more queues you add the worse the descriptor overhead will be. Generally I have found that about 6 queues is ideal. As you start getting to more than 8 the performance for 64B packets will start to drop off as each additional queue will hurt the descriptor cache performance as it starts writing back fewer and fewer descriptors per write which will increase the PCIe bus overhead for the writes. >> >>> perf top: >>> >>> PerfTop: 77835 irqs/sec kernel:99.7% exact: 0.0% [4000Hz >>> cycles], (all, 56 CPUs) >>> >>> --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- >>> >>> 16.32% [kernel] [k] skb_dst_force >>> 16.30% [kernel] [k] dst_release >>> 15.11% [kernel] [k] rt_cache_valid >>> 12.62% [kernel] [k] ipv4_mtu >> >> It seems a little strange that these 4 functions are on the top > > Yes dono why there is ipv4_mtu called and taking soo much cycles > >> >>> 5.60% [kernel] [k] do_raw_spin_lock >> >> Why is calling/taking this lock?
