the central server is a 16GB 2 processor sun workstation. It does not
swap. The repository contains 25308 change sets and the active file
set is 13781 files. There are a number of binary big files in it
(2-4MB). I have to admit, that it runs a pretty old version of
mercurial (0.9.5). We will upgrade eventually - would you expect
significant speedup?
Thanks for caring,
Ulrich
