Re: [K12OSN] LTSP CentOS5 slow



Hi Jones,

Please supply some specs of your server and how many TC's you are
connecting to it.Is this a default install of K12LTSP5, or CentOS5 with
ltsp on top of it? Have you updated the server since a default install?
The FF update shouldn't have hindered the performance any just,, FYI.
A few things to try. 
1. run top from a terminal while the server seems " slow ", and see if
your memory is all used up,or if cpu is 100%.
2. You could download jperf,and install on your K12LTSP server as well
as a (linux)laptop you have available. Plug your laptop into the switch
that the TC's are plugged into. Run jpef in server mode on the server &
run jperf on your laptop in client mode. You will see what bandwidth is
available along with jitter and all that sorta geeky stuff.This piece
has really helped me in finding were bandwidth is being used realtime.
3. Is the switch the TC's are plugged into a 'plug and play' switch? In
other words a non-managed switched?
4. That is odd Firefox is throwing that error you posted. Did you
install FF via yum? Is this error happening every time FF is launched,
or hit and miss?
You can download the jperf rpm at the URL below. You will need to
install iperf, first, which is at the url as well.

 ftp://eazylivin.net/server/jperf/

Let us know your findings.

Take Care,
Barry Cisna
