The number of client computers connected to our K12LTSP network keeps
increasing. It is currently 14 clients soon to increase to 20 or more
with the addition of a new classroom. Most clients are very similar
Compaq Deskpro DPENS P2 or Celeron 350 or 400MHz.
Our current server hardware is AMD 2500XP Desktop, 2GB RAM, 160GB SATA
HD, GigaLAN
Each of the 3 (soon to be 4) classrooms has their own 10/100 switch that
feeds into a 100/1000bit switch that connects to the server. All are
unmanaged switches. There are also a few windows computers that connect
to the system and authenticate against the K12LTSP server using SMBLDAP.
The K12LTSP server also acts as a file server for the windows computers.
During a newspaper production project, when we had more than ten clients
running simultaneously using Scribus and OpenOffice or Firefox, things
slowed down a bit and we had a few crashes. Increasing RAM from 1 GB to
2 GB seemed to help somewhat but not completely.
I am thinking that I will have to upgrade the system somehow to
accomodate the new clients, and generally to be able to deal with higher
peak usage.
Below are some options I have thought of. Which would be the best
option? Any other suggestions?
1.Upgrade from a "desktop" computer to a server specific motherboard/CPU
including SCSI drives etc. This seems expensive, and I am not sure of
the real benefit of a "server" over "desktop" at the same CPU speed etc.
2.Add another similar desktop box and use load balancing as explained in
WIKI.
3.Add another similar desktop box and use it as an application server
for openoffice/ firefox etc.
4. Enable local applications for firefox and openoffice. Could also be a
solution for sound problems (Mplayer) too.
5.???
What is your advice?
Thanks.
