[mohaa] server performance

[morphiend]

On my P2-400 server, I have 0% nice, and the rest, basically, of the CPU
going to user at 70%+ when >10 users. I've noticed this though too:

Under 5 users, the system plays as it should. Pings are where they're
supposed to be. Lag is not noticeable, to non-existant. 
Once 5 players have been reached, then the pings go up, but the lag is
still low->none. 
Next barrier comes at 10 users. This is the point that even the LAN
players that join the server's ping reach 100. 
After 12 users it's all downhill. Lag is extremely noticeable for
everyone and gameplay severely suffers.

Once again, the system stats are as follows:
P2-400
256MB of RAM
partial OC-3 (~36Mbit).

During play, here's the line from TOP w/ 16 players on the server.

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
10740 -----     14   0  156M 145M  3288 R    76.1 58.0  1308m

The only thing kind of disturbing is the load averages during that play
time:
load average: 0.73, 0.62, 0.72

Here's an example of load averages w/ 10 players on the server:
load average: 0.36, 0.62, 0.72
  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
10740 -----     19   0  156M 145M  3288 R    49.1 58.0  1311m

Pondering,
Mike

That's very odd - according to my system, I show 0% NICE. What user are
you 
running the servers under? I run it under a regular non-root user.

also..where did you get your context switch information
