[K12OSN] Terminals running sloooow

[Krsnendu dasa]

Very handy thanks. It seems I only have 1 GB of memory. I will boost that to
2 GB.
I also noticed the following when I ran top

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
16907 dilip     39  18 81308 6828  28m R 45.6  0.7  13478:09 firefox-bin
 7226 suki      39  18 30408 1196 1932 R 45.6  0.1   5162:57 gnuchess
21402 krsnendu  15   0 13740 6428 6300 S  2.2  0.6   0:11.14 nxagent

The top two processes have been using a lot of CPU for a long time from what
I can see. These user are certainly not logged on. They are primary school
students and it is 5am. Right now. What causes these processes to linger and
how do I get rid of them.
In this case I typed kill 16907
kill 7226
and it got rid of them. I guess that will help things go a bit faster. Am I
on the right track?
Some background on what top tells me would be very helpful.

We have version 1.1.2 Is that ok or should I upgrade to a more recent
version? And if so how do I do it? Up2date doesn't always seem to work.

I hope the version of OO is later than 1.12. Earlier version had a
problem that the file pspfontcache grew very large and slowed OO. IAC
try deleting this file in users home subdirectory for OO.

$free -m 
will show you how much memory. You can also run top and the first few
lines give the memory and usage status.

Try iptraf if you feel network slow down / chocking is the issue.
Although from specs you have mentioned this should not be so.

I did take liberty in snippings.
