Ed,
Thanks for the reply. How "run out of steam" is it at 25? Minor
lags or twiddling thumbs lags?
We will probably have about 10 or 15 clients to a server but Flash
is pretty processor hungry and used in a fair amount of
"educational" web sites.
I agree with you that RAM is key, anything to keep out of swap
space and avoid disk hits. I don't think we'll be doing lots of
writes to the disk so I'm trying to avoid the cost of SCSI RAID. We
built a server last year (Win2k) and the SCSI card alone was about
$400. It's cheaper imho just to stick in an extra server or two.
After all, we really aren't serving that many files.
Again, thanks. That's the kind of info I was needing.
Regards,
William

I don't have any experience with the Athlon 64, but I find a P4
3GHz starts to run out steam with 25 clients running everyday apps
such as OpenOffice simultaneously. RAM is probably the key part of
the equation - I use 2GB RAM on a P4 with 20 workstations. This
seems to be a working well for me. This is with ordinary IDE
drives - no problem there although I guess SCSI would improve
things. My clients are P1's with 64MB or 32MB RAM.

We are looking to replace a school lab full of standalone PCs
(Dell 1.6ghz Celerons) with LTSP. I'm wondering what a good
client to server ratio would be using something along the lines
of a Athlon64 3200 with a 10k SATA drive for the server. Mind you
that we may have all the kids hitting Flash driven web sites at
the same time and performance shouldn't look shabby compared to
the stand alones.
The lab is the first step to converting the rest of the school.
Also, any perceptible difference in using, say 533mhz Via Eden
motherboards for the clients vs. 1 ghz Edens?
Many thanks in advance.
