Description
Hello,
I've encoutereed this very strange and very annoying issue.
After some traffic on my VM guest performance start degarding in an orrible way, I'll make an example:
- Just rebooted host and guest: wget of 1GB file, resulting speed is 112MB/s, both on host and VM.
- Start rsync from VM, after some times I see that it's starting transfer data slowly and so i stop it.
- Now wget of 1GB file from host: 112MB/s but from guest: 1MB/s -> that's terrible!
- If i reboot the guest the speed increase again for some times, then go down quickly.
I've tried both vswitch and bridge, i tried also disable offloading both on host and guest, but nothing helped me 
The host is with xenserver 7 and all hotfixes installed.
Do you have any idea?
thank you very much
