Just a few random opinions/thoughts on the topic.

* more components (nfs, fs, lvm, ...) uses more stack space
* xfs eats stack this is why it's not really good on 32-bit (4K stack)
* performance diff vs. ext3 varies not only with work load but also with 
hardware
* ext3 is much more widely used and wont cause you any head aches when a new 
kernel arrives
