[PVE-User] performance of 4.2 versus 3.4

[miguel gonzalez]

Yes, i have read that. Is it safe to use it with software raid? I have read in proxmox forums that some people dont recommend it.

Another question about this. I have qcow2 with ide virtual hard drives. I had no cache and tried writeback but dd tests results are more or less the same (around 40 mb/s). 

Regards

Miguel
