ext3 has gone through updates for example, the block reservation patch.  
http://lwn.net/Articles/81357/ and the ext2/3 defrag tool has not been 
updated in a long time basically because it isnt necessary. You really 
dont want to run an unmaintained tool like  that on your filesystem just 
for the kicks
