The benchmarks I have seen have put Ext3 AHEAD of XFS for fast large 
file deletion. To quote from SGI's own paper 
regarding XFS deletion:

"One shortcoming can be the poor file deletion performance,
which is constrained by synchronous disk writes"

Certainly on my XP2100 system, a delete of a 4GB file on 200GB ext3 fs 
takes less than a second.
