For ext2/3 filesystems created ages ago:

man tune2fs, see "-O" and "dir_index"

For recently created (probably less than 2 years ago), perf should be good.

Last time I checked with big directory strucutres the performance 
difference for file listing between xfs, ext3, reiserfs and jfs was 
negligible.
