Hi guys --

I just received several inquiries from labmembers asking how to check
and then kill extra processes (I didn't leave instructions on the
labmembers at snf note -- it is good to know that people do seem to care!) 
Jeff sent this along, which seems good to me, and seems like would be
good to send out to labmembers -- but I wanted to check with you first. 
If it meets with your approval, I'd like to send it out (unless you are
planning to send one out...)  Please let me know --

While visiting SNF and working in the clean room I found that many
don't know how to check background processes and kill them. You might
to let people know how to do this. e.g.

$>ps -u [username]
$>kill -9 [process id]

where process id is from the first column of the ps -u output.

I showed this to a few people and most of them found they had several
instances of mozilla etc. running in the background.

Hope this helps.

Subject: Slow Coral...

Greetings --

I understand from the Coral Development Team that when response time on
Coral is slow, nowadays, it's almost always because of non-Coral related
use of the system.  Apparently, Mozilla, Netscape, and Star Office use
up a lot of system resources, particularly when people have multiple
sessions going on at once.

So, the recommendations are, as follows (at least as I understand them
-- I take full responsibility for inaccuracies or misunderstanding):

1.  Keep only one active session (please use and hang on to that SunRay
2.  Mozilla is the preferred browser (Netscape has a tendency to run
away and take up lots of computing resources)
3.  Close Mozilla and Star Office when not in use
4.  Use of remote Coral (which does not load the system) is encouraged

Please try to conserve computer resources -- if we all do, then there
will be no waiting to enable something...
