Interesting. Andreas said that it ran in 4 seconds.

On my Linux machine (2.4 GHz P4, 800MHz memory channel, 3.6g-2 VM with my 
mods) it runs in 250 msec or so (for about 4000 connections per second). This 
is starting the server first.

If I use the -notimer switch to the VM, and keep my mouse moving, it takes 
about 450 msec.

If I use the -notimer switch and don't move my mouse, it could take as long as 
9 seconds (or longer!).

However, if I start the client before the server, (even without the -notimer 
switch), I sometimes see it taking as long as 3.25 seconds or longer.
