[Xen-users] Poor performance on bandwidth, Xen 4.0.1 kernel pvops 2.6.32.24
Hello list,
I have two differents installation Xen Hypervisor on two identical
physical server, on the same switch :
The problem is on my new server (Xen 4.0.1 with pvops kernel 2.6.32.24), I
have bad performance on bandwidth
I have test with a files copy and "iperf".
Result iperf average:
Transfert
Bandwidth
XEN-A -> Windows Physical: 1005 MBytes 843 Mbits/sec
XEN-B -> Windows Physical: 522 MBytes 438 Mbits/sec
Windows Physical -> XEN-A: 477 MBytes 399 Mbits/sec
Windows Physical -> XEN-B: 175 MBytes 146 Mbits/sec
It''s the same network card but on the new installation, the module bnx2
have a new version...
Maybe i haven''t activate or forget something...
If you have an idea, I listen you !! Thanks in advance !

Re: [Xen-users] Poor performance on bandwidth, Xen 4.0.1 kernel pvops 2.6.32.24
Hello all,
I have tested on the new server XEN-B with the default lenny install,
kernel 2.6.26-2-amd64, i have the driver bnx2 with version 1.7.5 and the
result of iperf is perfect (average 900Mbits/sec on bandwidth)
So I think is the version of driver bnx2 (2.0.2) on the pvops kernel
2.6.32.24 who raises worries.
Someone have the same problem ? How I can bypass this ?
Really thanks in advance for your answer !!
For information, I''m on debian Lenny 5.0.6 with a Dell PowerEdge 2950

Re: [Xen-users] Poor performance on bandwidth, Xen 4.0.1 kernel pvops 2.6.32.24
Hello Olivier Hanesse and thanks for your answer !!
It''s good to know this ! So now I would like to know the diffrence
between
you and me... What''s your network card and have you installed the
package
"firmware-bnx2" ?
Can you give me the result of:
#dpkg -l | grep firmware-bnx2
For me:
ii firmware-bnx2 0.14 lenny2 Binary
firmware for Broadcom NetXtremeII
and #lsmod | grep bnx
For me, just:
bnx2 63308 0
Really thanks,
Rémi

I have two differents installation Xen Hypervisor on two identical

Re: [Xen-users] Poor performance on bandwidth, Xen 4.0.1 kernel pvops 2.6.32.24
All is identical... I have no idea now... If someone can help me.. For resume, on my dom0 with Xen 4.01 and kernel pvops 2.6.32.24 I have an average of 140Mbits/s bandwidth whereas I have a gigabit network card Olivier Hanesse <olivier.hanesse@gmail.com> 23/11/2010 13:18 A Rémi BERNIER <R.BERNIER@grelier.com> cc Objet Re: [Xen-users] Poor performance on bandwidth, Xen 4.0.1 kernel pvops 2.6.32.24 lsmod | grep bnx bnx2 57273 0 modinfo bnx2 filename: /lib/modules/2.6.32-bpo.5-xen-amd64/kernel/drivers/net/bnx2.ko firmware: bnx2/bnx2-rv2p-09ax-5.0.0.j3.fw firmware: bnx2/bnx2-rv2p-09-5.0.0.j3.fw firmware: bnx2/bnx2-mips-09-5.0.0.j3.fw firmware: bnx2/bnx2-rv2p-06-5.0.0.j3.fw firmware: bnx2/bnx2-mips-06-5.0.0.j3.fw version: 2.0.2 license: GPL description: Broadcom NetXtreme II BCM5706/5708/5709/5716 Driver author: Michael Chan <mchan@broadcom.com>srcversion: 8F18532C0D4FFBC79D95E9D alias: pci:v000014E4d0000163Csv*sd*bc*sc*i* alias: pci:v000014E4d0000163Bsv*sd*bc*sc*i* alias: pci:v000014E4d0000163Asv*sd*bc*sc*i* alias: pci:v000014E4d00001639sv*sd*bc*sc*i* alias: pci:v000014E4d000016ACsv*sd*bc*sc*i* alias: pci:v000014E4d000016AAsv*sd*bc*sc*i* alias: pci:v000014E4d000016AAsv0000103Csd00003102bc*sc*i* alias: pci:v000014E4d0000164Csv*sd*bc*sc*i* alias: pci:v000014E4d0000164Asv*sd*bc*sc*i* alias: pci:v000014E4d0000164Asv0000103Csd00003106bc*sc*i* alias: pci:v000014E4d0000164Asv0000103Csd00003101bc*sc*i* depends: vermagic: 2.6.32-bpo.5-xen-amd64 SMP mod_unload modversions parm: disable_msi:Disable Message Signaled Interrupt (MSI) (int) Voilà :) 2010/11/23 Rémi BERNIER <R.BERNIER@grelier.com> Thanks !!

Olivier 2010/11/23 Rémi BERNIER <R.BERNIER@grelier.com> Hello Olivier Hanesse and thanks for your answer !! It''s good to know this ! So now I would like to know the diffrence between you and me... What''s your network card and have you installed the package "firmware-bnx2" ? Can you give me the result of: #dpkg -l | grep firmware-bnx2 For me: ii firmware-bnx2 0.14 lenny2 Binary firmware for Broadcom NetXtremeII and #lsmod | grep bnx For me, just: bnx2 63308 0 Really thanks, Rémi Hello, Between 2 lenny dom0 with pvops kernel "2.6.32-26~bpo50+1" from debian backports, bnx2 (version 2.0.2) module seems good. I got "1.10 GBytes 941 Mbits/sec" Regards Olivier 2010/11/23 Rémi BERNIER <R.BERNIER@grelier.com> Hello all, I have tested on the new server XEN-B with the default lenny install, kernel 2.6.26-2-amd64, i have the driver bnx2 with version 1.7.5 and the result of iperf is perfect (average 900Mbits/sec on bandwidth) So I think is the version of driver bnx2 (2.0.2) on the pvops kernel 2.6.32.24 who raises worries. Someone have the same problem ? How I can bypass this ? Really thanks in advance for your answer !! For information, I''m on debian Lenny 5.0.6 with a Dell PowerEdge 2950 Rémi Hello list, I have two differents installation Xen Hypervisor on two identical physical server, on the same switch : The problem is on my new server (Xen 4.0.1 with pvops kernel 2.6.32.24), I have bad performance on bandwidth I have test with a files copy and "iperf". Result iperf average: Transfert Bandwidth XEN-A -> Windows Physical: 1005 MBytes 843 Mbits/sec XEN-B -> Windows Physical: 522 MBytes 438 Mbits/sec Windows Physical -> XEN-A: 477 MBytes 399 Mbits/sec Windows Physical -> XEN-B: 175 MBytes 146 Mbits/sec It''s the same network card but on the new installation, the module bnx2 have a new version... Maybe i haven''t activate or forget something... If you have an idea, I listen you !! Thanks in advance !
