I am now running my Ace-s on a Linux server with 1 Gb of ram, but
will move them to a dedicated Ace-machine soon, with only 500 Mb of ram.
I was wondering about the cache-sizes and performance issues: should I
use specific cachesizes for the small (few hundred Mb on disk)
local-running Ace-s, accessed through Xace, different from cachesizes
for the server(s) running on the same server?
The small servers are pretty fast with the default values of
4000/4000, but the big ones (several Gb on disk) can be pretty slow.
Shouldn't I be able to speed the big server and/or xace up significantly
by increasing my caches?
