Eneko,
Thanks for the feedback. It seems that the whole Windows system is slow. It
happens with loading applications too and loading start menu for example so
if I am understanding this right, viritio drives which are installed after
Windows is installed may not help me a lot?! Please correct me if I am
wrong. Also how can I build a virtio drive to test it?
*Below are results of pveperf. Is this very bad?*
root at hp:~# pveperf

AVERAGE SEEK TIME: 29.30 ms
FSYNCS/SECOND: 9.63
