There are no kernels at this date with 2.4.x only on legacy servers
The only ones for active linux distributions are 2.6.x or 3.x

The recommended distro to use : Debian (Wheezy)or Ubuntu 12.04 LTS

http://packages.debian.org/testing/database/firebird2.5-superclassic

https://help.ubuntu.com/community/Firebird2.5

They are the most used server side distros on the planet

ext4/xfs and ext3 by default are very safe , only when you need some speed tweaks you can play with filesystem parameters
if you care about your data please leave them untouched

you can check some performance numbers from the past
but these benchmarks could be wrong with the newer kernels 3.x

So the safe and fast are : ext3, ext4 , xfs

The best configuration is to leave it by default (it is enabled)
