Re: ESXi client / NFS server performance

[Emille Blanc]

The NFS server (4.8 release) from which the exports are mounted is a 
virtual guest on the ESXi 4.1 host.
Transfer rates to/from the virtual NFS server guest to another guest are 
a little faster on average (which makes some modicum of sense in my 
mind...) than from the NFS guest to a physically separate machine.

The VM guests are using em(4) if that's any help.

But, from the ESXi console it sucks.

Was your NFS server physical or virtual?

This may be a bit late, but for what it's worth, 4.8 -release as an
ESXi
4.1 client without any knob tweaking and pf running the default
ruleset.
Haven't done anything with ESXi 3.5 though, so I'm not sure what to
say on
that front.
