It does help. If data changes, it is first updated in the cache. New
data is served directly out of the cache, while the hard disk is synced
in the background. That's unless I am majorly mistaken about how caching
works.

Do you have some real numbers? I am not trying to doubt you too much. I
am genuinely curious how big the speedup is and if it is worth the
effort. All I wanted to point in my post is that the speedup is probably
not that great, but I'd really like to see benchmark numbers if someone
went to the trouble of doing it.

That's pretty relative. $70 for 512MB is not cheap for me. One reason
why my poor "server" is still running with 2x512MB *PC133*.

Well, you may be right. I guess I could try serving two trees and do
some tests myself.
