I heavily suggest updating to the SuSE 2.4.7 kernel. There are several
important fixes (also reiserfs related) in there.

Its the default IIRC.

How much RAM do you have? I just tried placing 600000 1k files in one
directory and it takes about 180MB of RAM to list it. considering that your
system will also stat those files I guess it will take a lot more memory for
it to perform reasonably well.

All depends on the hardware. If you don't have enough RAM to cache the
required information it will become too slow.
