Re: [ovirt-users] Bad performance with Windows 2012 guests
Hi, Ever since our first Windows Server 2012 deployment on oVirt (3.4 back then, now 3.5.1), I have noticed that working on these VMs via RDP or on the console via VNC is noticeably slower than on Windows 2008 guests on the same oVirt environment. [snip] Does anyone share this experience? Any idea why this could happen and how it can be fixed? Any other information I should share to get a better idea? Hi Martijn, Can you please provide the QEMU command line, together with kvm and qemu version? This information will be helpful for reproducing the problem. However, if the problem is not reproducible on a local setup, we will probably need to ask collecting some performance information with xperf tool. Sure!

Using a Windows 2012 VM on the same system it's only 33MB/s on 4k random with 32 queues and 300MB/s sequential writes. Similar tests with a linux VM show a bit better values than the Win2k8 R2 and respond ultra-fast. My hosts are connected via iSCSI using a 10 GbE link and a ZFS appliance as the storage system.
