Re: [GENERAL] Performance while loading data and indexing

I have seen various benchmarks where XFS seems to perform best when it 
comes to huge amounts of data and many files (due to balanced internal 
b+ trees).
also, XFS seems to be VERY mature and very stable.
ext2/3 don't seem to be that fast in most of the benchmarks.

i did some testing with reiser some time ago. the problem is that it 
seems to restore a very historic consistent snapshot of the data. XFS 
seems to be much better in this respect.

i have not tested JFS yet (but on this damn AIX beside me)
from my point of view i strongly recommend XFS (maybe somebody from 
RedHat should think about it).
