Greetings, It appears that I am having some major slowness issues on a HP Proliant DL380G4 after a fresh install of OpenBSD 4.2 i386 single processor kernel
When running a iperf (http://dast.nlanr.net/Projects/Iperf/) test to a Linux host on the same physical subnet on the same physical switch we are seeing around 4Mb/sec on a Gigabit broadcom card. After changing the net.inet.tcp.sendspace and net.inet.tcp.sendspace to 262144 and running iperf again we see the speeds jump up to around 72Mb/sec which still seems slow since linux hosts on the same subnet are getting around 757Mb/sec on similar cards and hardware. I checked and my net.inet.ip.ifq.maxlen is set to 256 Should I be running a different test then iperf? Any thoughts on why I am seeing such low numbers for a Gigabit card? Any suggestions for system changes I should make? Any help is very much appreciated. The outputs of the iperf tests and dmesg are below. # /root/iperf-2.0.2/src/iperf -c 192.168.129.86 -d ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 16.0 KByte (default) Client connecting to 192.168.129.86, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 6] local 192.168.129.86 port 35490 connected with 156.40.133.188 port 5001 [ 7] local 192.168.129.86 port 5001 connected with 156.40.133.188 port 52430 [ 6] 0.0-10.0 sec 5.12 MBytes 4.29 Mbits/sec [ 7] 0.0-10.1 sec 5.54 MBytes 4.61 Mbits/sec # sysctl -w net.inet.tcp.sendspace=262144 net.inet.tcp.sendspace: 16384 -> 262144 # sysctl -w net.inet.tcp.recvspace=262144 net.inet.tcp.recvspace: 16384 -> 262144 # /root/iperf-2.0.2/src/iperf -c 192.168.129.86 -d ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 256 KByte (default) Client connecting to 192.168.129.86, TCP port 5001 TCP window size: 256 KByte (default) ------------------------------------------------------------ [ 6] local 192.168.129.86 port 45594 connected with 156.40.133.188 port 5001 [ 7] local 192.168.129.86 port 5001 connected with 156.40.133.188 port 50890 [ 6] 0.0-10.0 sec 86.0 MBytes 72.0 Mbits/sec [ 7] 0.0-10.0 sec 85.0 MBytes 71.1 Mbits/sec Dmesg: OpenBSD 4.2 (GENERIC) #375: Tue Aug 28 10:38:44 MDT 2007 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Xeon(TM) CPU 3.60GHz ("GenuineIntel" 686-class) 3.61 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,DS-CPL,EST,TM2,CNXT-ID,CX16,xTPR real mem = 3757613056 (3583MB) avail mem = 3650039808 (3480MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 12/31/99, BIOS32 rev. 0 @ 0xf0000, SMBIOS rev. 2.3 @ 0xec000 (58 entries) bios0: vendor HP version "P51" date 08/26/2004 bios0: HP ProLiant DL380 G4 pcibios0 at bios0: rev 2.1 @ 0xf0000/0x2000 pcibios0: PCI BIOS has 7 Interrupt Routing table entries pcibios0: PCI Interrupt Router at 000:31:0 ("Intel 82801EB/ER LPC" rev 0x00) pcibios0: PCI bus #10 is the last bus bios0: ROM list: 0xc0000/0x8000 0xc8000/0x4000!
