Re: [Xen-users] nic poor performance after upgrade to xen 3.2
I think you use netfront to achieve such performances on domU
so you have to recompile in unmodified_drivers/linux-2.6 from Xen
sources under your domU
and load the kernel modules at boot time
xen-vnif.ko xen-platform-pci.ko xen-vbd.ko xen-balloon.ko
you must alias eth0 xen-vnif in modprobe.conf and of couse use netfront
instead of ioemu
in the vif part of your guest config file. But I think this step is
already done on your guest
otherwise you cannot achieve such a speed with vif type set to ioemu.

Hi,
I'm doing some test on a network 10 gb nics and xen
with version 3.1 i'm measuring 2.5 gb/sec from domU to an external physical
machine with iperf.
switching to 3.2 has reduced the measured performance to 40-50 Mb/sec.
did anything change in the network interface?
can someone help me?
thanks
