[ILUG] server slow down
[ILUG] server slow down

I have been given a couple of suggestions but I am having no success.
Other than the changes I made to samba, php and MySQL, I have a fairly
default installation of RH9. I also have Staroffice 7 and Mozilla
Firebird installed.
I described the symptoms as follows
When users load up the intranet homepage (from linux, XP or win98) it
takes about 15 seconds whereas in the past it was instant. It doesn't
make any difference if you use the ip address rather than the server
name.
When a user tries to save a document from staroffice to the server it
can take about 10 seconds to load the save dialog whereas before it was
instant.The default for saving is to the students home folder on the
samba server
Access speeds to another samba server and an older MS webserver have not
slowed down so I reckon it is something to do with this particular
machine and is not a networking problem.
Tried a different network card and restarting various services but no
change.

Checked the DNS server an all seems fine. I will set up an alternative
dns server this evening and try it with a couple of clients.

40% disk space free. Logs are rotating

As regards what process are running. I'm not sure how to give
information that is useful. The following is the result of ps -e l
