performance on large inboxes

I'm using ext3 with dir_hash. I considered using XFS, but there are a 
lot of benchmarks that show that XFS is not faster in general, also the 
XFS development seems to be stucked at the moment and from my own 
experience as well as from other people in a recent thread on this 
mailinglist there are some really strange errors appearing from time to 
time with XFS that are making it a bad choice for production systems, 
especially when it happens, that the server crashs unexpectedly (i.e. a 
memory module fails). I tried to trust ReiserFS several times and I had 
so much problems with it, that I don't intend to use it ever again. Even 
  Novell/SuSE which praised ReiserFS for a long time turned away from it.
