Is it possible that you are working with a fairly old linux distribution? Today's ext3 shouldn't have these issues any longer, otherwise Redhat wouldn't ship it as the only supported filesystem with its Enterprise distributions. A modern 2.6er ext3 has indexes and b-trees on top of the common ext3-layer, so even big directories shouldn't be a problem any more.
I use different systems ontop of Reiser4 and Reiserfs FS and CFQ as IO sheduler and can only recomend this commbination. And that for quiet long time. Especialy Reiser4 is very well perfomanced on big directories with small files, like emails are. CFQ is fast as needed.
