Subject: Re: vhost-net patches
Date: Fri, 23 Oct 2009 09:23:40 -0700	[thread overview]
Message-ID: <1256315020.4443.12.camel@localhost.localdomain> (raw)
In-Reply-To: <1256310765.4443.4.camel@localhost.localdomain>

Hello Michael,

Some initial vhost test netperf results on my T61 laptop from the
working tap device are here, latency has been significant decreased, but
throughput from guest to host has huge regression. I also hit guest
skb_xmit panic.

netperf TCP_STREAM, default setup, 60 secs run

guest->host drops from 3XXXMb/s to 1XXXMb/s (regression)
host->guest increases from 3XXXMb/s to 4XXXXMb/s 

TCP_RR, 60 secs run (very impressive)

guest->host trans/s increases from 2XXX/s to 13XXX/s
host->guest trans/s increases from 2XXX/s to 13XXX/s

Thanks
Shirley
