virtio disk slower than IDE?

[Gordan Bobic <gordan@xxxxxxxxxx>]

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.
