Subject: virtio disk slower than IDE?
Date: Sat, 14 Nov 2009 14:23:21 +0000 [thread overview]
Message-ID: <4AFEBD59.2090002@bobich.net> (raw)
I just tried paravirtualized virtio block devices, and my tests show
that they are approximately 30% slower than emulated IDE devices. I'm
guessing this isn't normal. Is this a known issue or am I likely to have
mosconfigured something? I'm using 64-bit RHEL/CentOS 5 (both host and
guest).
Thanks.
Gordan
