Many small files, best practise.

RHEL 5.3
~1000.000.000 files (1-30k)
~7TB in total


I'm looking for a best practice when implementing this using EXT3 (or some other FS if it shouldn't do the job.).

On average the reads dominate (99%), writes are only used for updating and isn't a part of the service provided.
The data is divided into 200k directories with each some 5k files. This ratio (dir/files) can be altered to
optimize FS performance.

Any suggestions are greatly appreciated.
