I have a server with dual Opteron processors, 3 GB
memory and two sata hardrive, the first hardrive is
38GB and 10000rpm hosting the root(/), while the
second hardrive is 250GB and 7200rpm hosting the home
directories (/home) of 1300 users. This server serves
41 clients, they all identical machines with Duron
1600 processor and 128MB memory. There are dual 1GB
network connections on the server motherboard, all the
switches (3 switches) used in this network have 1GB
ports. This system is installed in a secondary school
in UK, 33 clients are used in one teaching room
designed to accommodate 32 students, the other 8
clients are installed in the sixth formers study
centre to be used outside lessons. The server is
connected through one network port to the thin client
system and connected through the second network card
to the school network to get Internet connection. I am
using SuSE 9.1 pro and ltsp-4, I did a full
installation of SuSE 9.1 with almost all the packages
supplied with the distro in addition to Star Office 7.
As you can imagine when this system used for teaching
Star Office will be used by 32 students and the same
thing can happen with other packages like GIMP and of
course surfing the net by sometimes 40 clients at the
same time and some of them may play games over the
internet. My problem is with the login which is slow,
it may take 10 minutes for all 32 students to login
together, of course some of them will login faster
than the others. However, once every one login the
system speed is acceptable, of course loading Star
Office is a slow even in a stand alone computer. I am
using KDE as a user interface. Any advice of how to
speed up the system is appreciated.
