Hello 



In this link i see how improve the I/O in PVE when a image of disk is used, may be that will be better to do changes in the next release of pve-manager 

I don't have tested, but may be that someone can do it? 



io=native => for block device based VMs. 
io=threads => for file-based VMs.
