If you have the opportunity, I would suggest giving reiserfs v3 a try. I use reiserfs on my backuppc systems, and it works quite nicelty. Of course, depending on the speed/size of disks it can make a big difference as well.
It isn't easy to 'try' different filesystems because you either need a temporary medium to store all your backup data, and it also will take days/weeks if you truly have a lot of data which is kind of required else you wouldn't have performance issues in the first place.... In any case, if you (or anyone else) can, it would be really interesting to see the difference in performance between ext3 and reiserfs, since AFAICT, reiserfs is supposed to be very fast in handling small files, which essentially is what hardlinks are all about....
