Ext4 benchmarks

[Jean-Pierre Dion <jean-pierre.dion@bull.net>]

Hi all,

we already discussed during the conf calls what
benchmarks should be ran on ext4.

As we have OLS paper on the table we were thinking
here at Bull what bench t run and on which kernel.

If we want trying to compare ext3 and ext4, I guess we
should at least show that :
- ext4 has equivalent perfs than ext3,
- improvements done for ext3 are still in ext4 (mb alloc, del alloc...).

So  we were wondering what's best to do :
- run on 2.6.19 (includes del alloc and mb alloc if I am not wrong),
- run on 2.6.20 (lacks mb alloc),

- select relevant benchs (iozone...).

What do you think ?

Thanks.
