The performance difference between >90% full and 55% full will be large
on every filesystem.  When we ship a repacker, that will be less true,
because we will have large chunks of unused space after the repacker runs.

Oddly enough, I don't know the statistics for reiser* filesystems, but I
know that for FFS you should not let it become more than 85% full before
buying a new disk (or cleaning your home directory) if you want good
performance.
