Thanks, this information is really usefull, ok, I'm gonna buy this server:
2 Xeon Quad Core 3.0 GHz
8 GB Ram
4 ethernet ports
this server should be support 400 user, is this possible?

class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt \
0pt 0.8ex; padding-left: 1ex;"> Hi,<br>
<br>
we monitor for Server sizing the following values:<br>
- Number of processes and threads<br>
- nx agents / users<br>
- load average (15min, 1min, 15sec)<br>
- Total CPU usage (user, nice, system, IO, IRQ, SoftIRQ)<br>
- Memory usage (used, free, buffers, cached, swap)<br>
- CPU usage per nx agent<br>
- number of TCP connections<br>
=> all this values where messured by self written perl scripts and plotted with \
drraw (rrd graphing tool)<br> <br>
Out of this messurements we found out that our machine:<br>
<br>
SUN Fire X4100 (2x DualCore Opteron 2.2GHz, 16GB Memory, Dual PowerSupply, RAID1)<br>
<br>
Can support at maximum 100 user sessions without getting performance issues for the \
user.<br> <br>
The installation is a RedHat Enterprise Linux 4.6 with:<br>
- screensavers disabled (only black screen)<br>
- disabled gamin (gam_server)<br>
- disabled polling of virtual floppy/CD drive (provided by the service processor)<br>
<br>
It should be also possible to load the machine with a higher amount of sessions by \
providing a higher number of memory. Faster CPUs are not important (nothing should be \
computed on such a machine anyways) a higher number of cpu cores provides better user \
scaling. So maybe with a new X4100M2 with AMD QuadCore Opteron Processors and 8x4GB \
of memory it would be possible to provide 200 or more sessions on a single \
machine.<br>
<br>
This machine runs login sessions, shells, browser, some small interactive tools, \
everything taking more CPU or memory get's dispatched to the companies compute \
farm.<br> <br>
I think it would be nice when also other people post there results in session \
scalability here so we can compare and learn.<br> <br>
Cheers,<br>
Florian<br>
<br>
P.S.: Sorry but currently I am not allowed to post our monitoring scripts.<br>
