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

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

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

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