Re: [Xen-users] poor IO performance with dom0 on centos7

[Christoph <mangel@xxxxxx>]

Im afraid it wasnt the solution, with centos7 as domU it is much 
better/faster but I still have a IO problem on the NFS domU...
Any other hints for me to make it faster? (except buy new hardware, it 
was fast enough with centos6 as dom0)
