Hi Alec,
I'm Pierrick Louin working in the team of François-Régis Menguy @orange-Labs.
In our last experiments, using the NFVbench application, we came across some
issues and a workaround in trying to reach high performances from the bench at
a high line rate.
Maybe you can help us understanding what happens in the following observations.
The raw traces are joined as text files.
--------------------------------------------------------------------------------------------
Those reference tests are performed over a simple loopback link between the 2
ports of a NIC (either wired or through a hardware switch).
We studied the two following cases:
NIC Intel X520 (10 Gbits/s)
NIC Mellanox ConnectX-5 (25 Gbits/s)
Note that the list of the cpu threads reserved to the generator is not
optimized. There is room for tuning...
However this was not the point in these tests since, as we will see, the
performance issue appears related to the RX process.
The T-Rex generator will run with the same settings whether it is used
standalone or wrapped in the NFVbench.
TRex version: v2.59
NFVbench version: 3.5.0 (3.5.1.dev1)
We have slightly patched the NFVbench code in order to make some processing now
optional and/or configurable from the command line.
--cores Override the T-Rex 'cores' parameter
--service-mode Enable T-Rex service mode
--extra-stats Enable extra flow stats (on high load traffic)
--no-latency-stats Disable flow stats for latency traffic
We consider the smallest packet size (64 bytes L2) in order to assess the
maximum throughput achievable.
Four tests are performed for each of the NICs tested - with a 100% and NDR rate.
1) Preliminary tests, performed with a basic scenario: 'pik.py' launched from a
T-Rex console (derived from the script 'bench.py' coming with the T-Rex appli).
2) Tests performed using NFVbench (v3.5.0) in its native coding:
High-rate generic streams (for BW measurement) and Low-rate streams (for
Latency assessment) are configured into the T-Rex generator in order to allow
stats computing on transmitted/received streams.
3) Tests performed using NFVbench where we have disabled into the 'trex_gen.py'
script the instructions to tag the traffic generated for the purpose of further
statistics (as far as we understand it) - this change is made in calls to
STLStream().
4) Tests performed using NFVbench where we keep the flow stats property for the
latency streams only.
FIRST ANALYSIS
************
The T-Rex test allows us to check that we have no bottleneck on the
generator/analyzer + SUT side.
The NFVbench results show acceptable performances only when dealing with the 10
Gbits/sec line.
Using the NFVbench with its unmodified behaviour (case 2) the line rate is far
from being reached with a 50 Gpbs line:
8.56 Gbits/s instead of 50 Gbits/s (L1)
Unless there are some special reasons for activating a heavy flow stats RX
processing, we suggest working in the case (4).
We keep the latency assessment while the traffic counters seem to suffice at
measuring the BW performances.
Of course it may depend on the NIC capabilities for offloading traffic
measurements.
This is why we also make the flow stat activation optional.
FURTHER ANALYSIS
***************
However, looking closer to the performances obtained in the case (3),
we can see a significantly reduced rate at the TX (and therefore RX) side:
19.09 Gbits/s instead of 20 Gbps (L1) - value is stable between launches
48.42 Gbits/s instead of 50 Gbps (L1) - actually variable between launches
Note that the NDR measurement does not show any warning then.
This is not our target case but it made me thinking...
Thus, I tried a (5) case where we keep the flow stats for BW streams only.
- the TX packet rate is reduced as in the case (3) for the Intel x520
- the throughput is limited by the line rate for the Mellanox ConnectX-5
<=> this is unexpected regarding to our hypotheses.
CONCLUSION
***********
It looks like we are missing something in our comprehension.
Not sure that our workaround would not hide some side effects.
So far, we can use it for our present needs.
Waiting for reading from you.
Thanks,
Pierrick
