Re: [Xen-users] Poor performance on bandwidth, Xen 4.0.1 kernel pvops 2.
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.

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

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

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 !
