New Lab

[David Groos]

Hi Anthony,
In my classroom I'm using an older 2-chip, dual core (total of 4 processors)
server running at 2.8 GHz.  This server is running Jaunty.  It has just 3
gigs of RAM on it.  I've got 16 Pentium 4's, each with 512 MB on it running
as it's thin clients.  I'm running firefox locally.  I don't use Flash much
though it (finally) works ok though sound on our system is messed up.  We do
do online simulations which are often java based--this all happens as a
localapp--and they work fine.  We also run CmapTools as a localapp.  I might
be running OpenOffice locally (I'm trying to) but haven't been successful
checking.

Until I was running these apps as localapps, my whole system was pretty
slow--requiring user patience (often not getting it with good grace!).
However, since using localapps, even 2 at a time, things are just fine, just
as fast as my dual-core mac.  Kids have rarely complained about things being
slow since I started to use localapps on Jaunty.

When the other class tries to boot their thin clients using my server, that
is when I get too many clients booted against it, the server slows down but
if I had more ram (working to get some right now) I'm sure I could run the
32 users just as easily as the 16 because all are using localapps.

Good luck,
David
