Hello,
This patch :
kvm: qemu: remove SIGUSR2 from io_sigset
Applied 15th Jan 2008 looks to kill I/O performance for me. As soon as I
revert it my VMs are much faster. I don't really use SMP for my guests,
perhaps this patch has made uniprocessor VMs slower ?
The issue occurs even when using RAW images as well as QCOW2 it also
occurs if the guest is running Windows OR Linux.
Regards,
Will Trives
