You can find all about the diploma thesis Constantin Loizides
wrote on that topic under
http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/
Alas, while fragmentation effects are measurable, their real-world-impact
is so heavily masked by even the slightest differences in the VFS of
different Linux kernel versions and the usage pattern of applications
that it is hard to make a definitive general statement.
