I kinda doubt it's the server, but that 100Mbit network you mentioned 
does raise a flag.  Does that also include the connection to your server?

About 6 years ago, I had a dual-Athlon MP, 1.4GHz box with 3.5GB DRAM 
serving 24 clients daily, with simultaneous OpenOffice.org and Firefox 
sessions open (school computer lab), and that server had no problems 
with it.  Response (for that era) was snappy, and the K12LTSP server was 
not overloaded.  The difference was that I had a Gig-E connection to the 

Never, ever say no to a more powerful box!  I envy you.  :-)  If that 
server has built-in Gig-E, which I suspect it does, then make sure you 
have a Gig-E port on whatever switch you're connecting it to.  This is, 
as Joe Biden would say, a big...umm...deal.  :-D  Seriously, though, 
this is.  The clients can be 100Mbit, no problem, but the server should 
hook up to Gig.

I'm assuming that the CPU's are also more powerful than your current 
server.  Is this is 64-bit server, perchance?  If so, then you can run 
64-bit K12LTSP 5EL on it, but there are a few things to be aware of, 
especially with regard to Firefox and plugins.  Let us know, and again,
