Currently testing with Windows 2012 (so not sure how well the virtio drivers work on Win7 or others).

I downloaded and installed the latest virtio drivers as per the posts on proxmox wiki/sites. virtio-win-0.1-74.iso
All works... however, transfer speeds to the Windows 2012 machine are now 1/2 of what they were before.

I would get 40-50MB/s transferring files from my main work machine to the proxmox win 2012 machine using the e1000 setup.
Which is slow (to my other systems I get 70-90MB/s), so I thought I would try the virtio drivers.
Now I get 20-25MB/s :(

Are there tweeks I need to do on either proxmox or windows? Or just go back to the e1000 drivers?

Thanks,
 
I had to go back to the e1000. In my case under FreeBSD and years later, virtio does not function properly.
See proto://bugs.freebsd.org/bugzilla/show_bug.cgi?id=165059

Neither pfSense nor Kali Linux. VirtIO cost me weeks in debuggig webservers, analyzing tcp packets in deep and ping. Sadly the latter was the only thing I could get to work consistently using VirtIO. As soon as I switch to e1000 every service magicly works like a treat. VirtIO tends to parcially eat everything beond icmp.
