Greetings
I've searched to no avail so far... there is bound to be something more intelligible out there...???
I am playing with bonnie++ for the first time...
May I please get some advise and list experience on using this or other disk subsystem benchmark programs properly with or without a GUI ?
Test system in this case is a Compaq DL360 with 2 to 4 Gig DRAM and qty (2) 36Gig 10k drives in hardware raid1 (raid1 default 128k) and a smart array 5304 controller with 128 meg dram
The machine screams with this controller... yet I want to compare tests with it to the standard built in smart array controller etc
Ive read bonnie++ stuff till I cant stand it no more and am just not seeing the relevance in the end result vectors to something tangible.
Please advise and thanks in advance...

You have got this part right. bonnie++ was irrevelant...was because the guy has finally added an option to disable write buffering.
Try bonnie++ without write buffering...
However, that still does not make the results very useful...the best thing would be to simulate what your application would do to your disk subsystem and filesystem.
Here is an example of a good benchmark for those doing mail storage with the Maildir format:

Complete with the tools needed for you to perform your own tests.

The NetApp people used to have one called 'postmark' that was good for measuring the speed of creating and deleting small files. I've lost track of it, but I think the last time I mentioned it someone said it was packaged for Debian and available in their repositories.

IIRC, postmark also suffered from the lack of use of fsync...yes, it does suffer from that:

I've always used iozone to much satisfaction. Just make sure your file sizes are larger than your caching. The automatic options will reveal with the real boundaries are to your caching and then you can perform custom tests from there. Keep in mind to get good, relevant results, you're looking at very large files that'll take awhile to complete.
