I am using a ubd with ext4 sitting on an nfs server. The host, however, 
has more than enough memory to cache all of it, so it is pretty much 
like reading off a ramdisk as it is fully cached.

It is quite clear in that case.

I can retest with nfs (easily) and I can tweak the setup to retest with 
hostfs.
