[ovirt-devel] IO threads versus number of diske mapped to VM

Hi List I have trouble to find information regarding how to performance tune my IO on my VM. We see bad performance max 30 MB/s from the VM to the storage (Posix mounted file system) We have tested the filesystems locally from the Ovirt host , and we can easy get +500MB/s Found a parameter <io> <threads>2</threads> </io> I can't find recommended configuration regarding this parameter. My question is which value is should use for this , when having 60 high performance disks mapped to my VM Somebody any answers tnx
