>Caching the filesystem is *vitally* important for performance. But that
can be done in a very small amount of RAM. Assuming a single file entry
requires 100 bytes (which seems very high to >me), 300MB of RAM performing
caching (which is what my backup severs usually average) will hold 3
*MILLION* files.

So the below *would* warrant more RAM? Four GB RAM should be more than
enough. Correct?
"Pool is 1750.71GB comprising 4385533 files and 4369 directories (as of
2011-11-03 01:12),"
OTOH, I didn't see much performance improvement when I went from the
dual-xeon with 2 GB RAM and using ext3 to a quad-core with 4 GB RAM and
ext4. The disks were faster on the quad-core, but that's to be expected when
going from PATA-raids to SATA-raids I guess.
