I'm trying to run some IOzone benchmarking on a new system to get a

Unfortunately, the system has a lot of memory (144GB), but I have some
time so am approaching my runs as follows:

SvSAN does something similar and it does it rather well, I think.

Do you expect to be reading or writing 36 or 288Gb files very often on
this array? The largest file size

ZFS will always track per-user usage information even in the absence of

If you have compression turned on (and I highly recommend turning
it on if you have the CPU power to handle it), the

Unfortunately, benchmarking with IOzone is a very poor indicator of
what performance will be like during normal use. Forcing the system

5.3 is released, not much of an idea about the 5.4 schedule.

The problem is this box has 144GB of memory. If I go with a 16GB file

Sounds like IOzone may not be my best option here (though it does
produce pretty graphs).
bonnie++ actually gave me more
