Also- you might like to use:
lmktemp
Large Sequential I/O tests:
WRITE TEST:
cd /BIG
time lmktemp 2GBtestfile 2000000000
divide 2000/#sec for MB/sec write speed
READ Test:
umount /BIG (flush file from p690 memory)
mount /BIG
time cp 2GBtestfile /dev/null
divide 2000/#sec for MB/sec read speed
Run the tests while nmon (select a for adapter) runs in another window
you will see the throughput for each fibre channel adapter from p690 to ESS.

If you don't do this, your testing will be skewed. Next, just file off some "dd", "find", "tar" or "cpio" commands with the "time" command. Monitor with vmstat and iostat.

I would like to test my P690 and Shark through put. Dose anyone know of a good way to really push there system to see what kind of performance you can get. I would like to test the processors and the disk performance. Any ideas would be very helpful. Thanks in advance. Jeff Wilson System Administrator Great-West Life & Annuity Ins. Co.
