Christiaan,

As ZFS tuning has already been suggested, remember:

a) Never tune unless you need to.
b) Never tune unless you have an untuned benchmark set of figures to 
compare against after the system has been tuned - especially in ZFS-land 
which, whilst it may not be quite there, is designed to ultimately be 
"self-tuning". Putting stuff hard into /etc/system might be 
counter-productive to performance in the future (although hopefully by 
that time, it will be blithely ignored).
c) Never tune more than one parameter at one go.
d) Understand as fully as possible the wider ramifications of any tuning 
that you undertake.

If this is all "master of the bleedin' obvious" to you, then please 
accept my humble apologies - it is often not the case...

Regards... Sean.
