[PVE-User] Very slow install of applications in Windows 2008R2 VM on Proxmox - What is the cause?

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
CPU BOGOMIPS:      72530.72
REGEX/SECOND:      583443
HD SIZE:           94.49 GB (/dev/mapper/pve-root)
BUFFERED READS:    61.13 MB/sec
AVERAGE SEEK TIME: 29.30 ms
FSYNCS/SECOND:     9.63
DNS EXT:           70.07 ms

Regards,
