OpenVZ VM inside a Proxmox cluster inside Virtualbox using storage via NFS to Freenas created from 2 vhd's mirrored with ZFS also running in Virtualbox

All on a 2TB 7200RPM drive. Faster than I thought it would be.

Benchmarking with dd is silly for the following reason:

 

VFS cache.

VFS cache. 

sync && echo 3 > /proc/sys/vm/drop_caches

sync && echo 3 > /proc/sys/vm/drop_caches

sync is unnecessary, see vm.c in the latest kernel.. 3 is also unnecessary, a 1 will do, but the best way is to remount your filesystem so the entire page cache VFS layer is nuked..

Some real nice HDD RAID10 setup results

Got some 150MB seq read, 120 Write on my desktop single HDD (Using Windows & Crystal Disk Mark)...
If I can remember it correctly the benchmark was about 10% better when there was noting on the HDD and brand new...
