Thanks for the tip about bonnie++.
In my peak period of performance testing "diskio" was the benchmark.
I have been looking for "diskio" for a while and I found a working
version. They have been using it to test filesystems so a comparison
to the bonnie++ numbers would be interesting.

Here are the "diskio" URLs for those interested:
Latest "diskio" version seems to be 4.0
<<http://developer.osdl.org/dev/doubt/diskio/index.html>>

Newest posted "diskio" test results with kernel 2.6.14(Vanilla Kernel):
These tests run with "diskio" v3.0 on ext2, ext3, jfs, xfs, reiserfs:
<<http://developer.osdl.org/dev/doubt/diskio/graph/>>

I found this "DOTS" (Database Opensource Test Suite) test suite
which appears up to date and references the LTP project:
<<http://ltp.sourceforge.net/dotshowto.php>>

The LTP (Linux Test Project) page I found. No kernel newer than 2.5.
Makes me wonder if the project is still alive:
<<http://ltp.sourceforge.net/testresults/2001/results.php>>

These may be very out of date so I would appreciate pointers to more
current tests like bonnie++, which I had never heard of.

Interesting (to me, YMMV) side note:
The "diskio" testing is done in the OSDL "Doubt SIG" at:
<<http://developer.osdl.org/dev/doubt/>>
Their Mission statement is:

We want to trust system.
We do not want to believe in system.
What is DOUBT project?

DOUBT is project to create set of system invalidation checking programs.

DOUBT stands for
  	D 	oubt is
c      O 	llection of
  	U 	ncertainty checking
  	B 	road range
  	T 	esting tools

Catchy huh?
