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)

but I have new Infos, I have installed a new kernel 4.1.6-1.el6.elrepo.x86_64 and the problem is gone! the original centos6 kernel seems to have some nfs/io issues (kernel-2.6.32-573.3.1.el6.centos.plus.x86_64)

have tried nfs server with other domU sentos7 based and there is all ok to...

so, dont use centos6 domU's on centos7 dom0 (or use a newer kernels)
