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

Hello, I got the backports version : dpkg -l | grep firmware-bnx2 ii firmware-bnx2 0.24~bpo50+1 Binary firmware for Broadcom NetXtremeII Hope this helps. Olivier 2010/11/23 Rémi BERNIER <R.BERNIER@xxxxxxxxxxx> 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@xxxxxxxxxxx> 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 !
