jwoolen Posted January 29, 2021 Share Posted January 29, 2021 (edited) I recently added a new Windows 10 VM to my UnRAID server using Q35-5.1 and virtio-win-0.1.190.1 and and I noticed when copying from the VM to the cache drive it was significantly slower than an older VM running Q35-4.2 and virtio-win-0.1.173-2. To verify, I cloned the old VM template and did a fresh Windows install and confirmed that it was much faster than using Q35-5.1 and virtio-win-0.1.190.1. I also tried i440fx-5.1 , but it was slower than Q35-5.1. Is this a known issue?

jwoolen Posted January 29, 2021 Author Share Posted January 29, 2021 Thanks Vr2lo! That fixed it. Do you know why this is necessary? Quote Link to comment
jwoolen Posted January 30, 2021 Author Share Posted January 30, 2021 What’s crazy is that I changed it back to 8 and it still works. Quote Link to comment
jwoolen Posted February 7, 2021 Author Share Posted February 7, 2021 I set up a few more VMs recently and I found out that the culprit was the virtio-net setting under Network Model in the VM configuration. When I used virtio I didn't have any problems. Quote Link to comment
