Hi list,
I am tired of "syntetic" benchmarks and i wrote a script to totally
automate benchmarking for various file system (command line option)
through the same partition, collect the data and show results in a
nice way.
There are 4 basic benchmarks performed, copy, compress, uncompress and
delete. The data folder i used is the linus-source-2.6.30-rc5
(uncompressed).
The script can be downloaded here:

help)
Here are some results for core2duo, Western digital green power hard
disk (WD5000AACS):

Btw, it might be roaches in the code:
transparent compression should win 20-25%...

It seems that btrfs has good performance, except for delete times.
