That's one of the major problems with Windows Terminal Server; the underlying platform's just not efficient. The RDP protocol used with it is reasonably efficient, but the server itself gets S-L-O-W very quickly. I never did more than five on a dual-PIII, 900MHz, 1GB DRAM box w/ Ultra3-SCSI RAID, back when I was running Windows networks, for performance reasons; with any more, the CPUs kept pegging, and the memory subsystem kept almost continuously swapping to disk. As it was, there was plenty of swapping, and the CPUs were heavily used. We also had stability issues with user applications (e. g. Microsoft Office). We ended up using Terminal Services only for us sysadmins and making everyone run MS Office on their desktops again. Boy, did we learn!
If for some reason you have to do this for twenty clients on one server, then I'd recommend going for, at a minimum, a four processor box, with max GHz (currently we're talking either Xeon 3.2GHz's or Opteron 2.2GHz's (that's the 848 model, BTW). Also, better have no less than 4GB DRAM, and more is definitely not overkill.

Ooops that's a P-III & just for clarification we're using K12LTSP with diskless client, from each client we launch a rdesktop session.

Hi,
Has anyone setup rdesktop with linux on 20 + workstations ? (With Win2K) and what specs are needed for the Win2K server to handle the load.
We've setup a P-II 500 Mhz with 512mb ram and can barely launch 3 connections. The response is incrediblly SLOW....
thanks for the input

I have 3 schools, all connected via fiber. There are approx 30 classrooms per building, with a variation of 10 & 100mbit connections internally. The 2 big directions I'm looking at would be to have 90 "mini-labs", where a teacher gets a new white-box Pentium 4 computer, and have it serve as a classroom LTSP server to 5 or 6 "junker" thin clients for the students (much like the original case study Paul Nelson put up several years back). If the student management system won't work under Wine -- that teacher computer would have to run win4lin or some such solution.
Instead of win4lin think about using a Windows terminal server with
rdesktop. ....you will need to spend a little but I suspect you will be
able to conqueror this application requirement.
