- Is this 2.9GiB/s or 2.9 MiB/s?

- Are you testing using NFS in all versions?i am using the v3 version
- What is the disk format?partion size format/ 20Gb xfsswap 2 Gb xfs/dados rest of disk xfs (note, this is the partition where i save the ISOs,exports and VM disks)
- How do you test io on the host?I do a clean install of centos and do the test before i install the ovirt
the test:
http://pastebin.com/7RKU7778- What kind of nic is used? (1G, 10G?)Is only a 100mbps :(100Mbps will not get you more than several MB/s. 11MB/s on a very bright day...We need much more details to understand what do you test here.I have problems to upload the benchmark test on orvirt to novabench site, so here is the screenshot(i make a mistake on the last email i get the wrong value), is 86 Mb/s:Which is not possible on the wire. Unless it's VM to VM? And the storage is local, which means it's the bandwidth of the physical disk itself?Y.______________________________
And the novabench on xenserver:
https://novabench.com/compare.php?id=ba8dd628e4042dfc1f3d396 70b164ab11061671 - For Xenserver - detailed description of the vm and the storage configuration?The host is the same(i install xenserver, do the tests before i install centos), the VM i use the same configuration of ovirt, 2 cores, 4 Gb of ramand 60 Gb disk(in the default xenserver SR)
- For ovirt, can you share the vm command line, available in /var/log/libvirt/qemu/vmname.log?
