*nix has less of a problem with this than DOS did. For any filesystem
and operating system there are parameters than can affect performance.
You usually won't need to tweak these at all, even with a couple of
thousand files. This falls under the Rules of Optimization (paraphrased
from memory, sorry):

1. Don't do it.
2. Don't do it yet.
3. Profile. (optimize the right thing)
3. Measure before and after. (did you help or hurt?)

If you want to see examples of a NEED to tweak, and how to do it, Google
for what people have done for running NNTP servers (absolutely HUGE
numbers of small files, which are added and removed continuously). *IF*
you need to tweak, you must take into account your particular situation.
