Hi,
we were testing the network throughput with some simple wget tests,
grabbing a 112MB file off another machine, the host OS gets 46MB/sec
transferring that file, but the guest virtual ones only get 10-14MB/sec,
I'm using model=rtl8139 for the nic, and a tap via a bridge, I'm
wondering if I'm doing something wrong, is there another nic model I can
use to make it faster? or use a different method besides the network tap
+bridge thing?
I tested two guests pulling the same file at the same time, both got
~10MB/sec, so it seems the host is up to it, but the guests are somehow
limited..
I saw some patches for an "IOQ" driver, should I be using a different
kernel tree?
I'm using kvm-40 and linux 2.6.23-rc6
