there can be several reasone:

(1) xp uses a journaling file system (and unless you use xfs or reiser 4 
on unix, journaling slows down there as well)
(2) all filenames have to be uncoded

The unicode aspect is also the reason why kpsewhich on windows is slow: 
after loading the database all names need to be converted to unicode and 
comparison be done at that level; this is why on windows kpse is a 
deamon which then makes it fly (esp when system calls are made from tex 
to other tex related programs)
