Re: [Ltsp-discuss] ltsp performance/benchmarking & virtual clients

Hi, I've recently been testing ltsp running on xen virtual machines. I'm infact writing this email on a terminal whose server is sharing the hardware with another virtual server exporting /homes. My notes are in Spanish but there's plenty of help on the net. Let me know if you run into problems

Hi! As a part of my masters degree in Networking and Systems administration at Oslo university College, some fellow students and I are conducting an experiment about terminal servers. We are trying to specify the bottlenecks of a setup with any given hardware. At present we are using a p4 2.4 with

Yes, IceWM is good enough but I don't have a choice but to use either KDE or Gnome for this project. In connection with this, which of the two is much faster to use for this kind of an LTSP setup? I don't know. KDE was considered more "bloated" (or complicated for fans ;o) than GNOME, however the

Hallo, Marvin It depends how responsible system do You want to have. I'd assume approx. double the users that Craige suggested, however I have no direct contact with such a large installation. It also very depends on some decisions, settings and tweaking. One big decision is WM/DE. For example

Hi Marvin, We've been running an LTSP server on a Xeon system quite similar to yours but with 2 GB RAM. There are 25 terminals connected at the moment, but not all of them are in use at the same time. Yesterday was the first time I saw 20 users logged in concurrently. No problem so far. We are
