Hi! I always used Red Hat/Fedora Core on many servers, but last month I came with a new project: Fedora as a LTSP server. Anyone here has done it? I'm asking because I'm getting some difficulties. I read many things about LTSP and many people said that they were supporting like 30-40 users on a P4 2.0 Server with 512mb of ram. "That's great!" - I thought. So I began installing a LTSP server on Fedora. I did everything ok and got the server and clients working fine. I began logging in on the clients, and when I got 8 to 10 users logged at the same time, the load average on server was SO HIGH! 15.0! Everything just started to get lagged and unusable. Since the guys told that they did many clients at the same time, I began trying to fix this problem: 1) Mounted the root partition with the noatime option, saving I/O access. 2) Prelinked EVERYTHING on the system 3) Tweaked KDE and kded (this one was eating a lot of cpu) 4) Turned off all services that I didn't need 5) Tweaked HD with hdparm And the results: same thing. I tried with three different servers: First: Fedora Core 3, latest kernel (2.6.10-1.766_FC3) KDE 3.3 as Window Manager of choice Celeron 2.0Ghz 1.5GB RAM 120gb HD Second: Fedora Core 3, latest kernel (2.6.10-1.766_FC3) XFCE as Window Manager of choice Semprom 2.0Ghz 512MB RAM 40gb HD Third: Fedora Core 3 (x86_64), latest kernel (2.6.10-1.766_FC3) KDE 3.3 as Window Manager of choice Athlon64 2.2Ghz 512MB RAM 80GB HD All the same results: High load average, high usage of cpu, no memory problems (no heavy swap usage) and all clients so slow! :( I tried many things, then a friend who has done that sugested me to try another distro, and I tried a KNOPPIX based one just to test. Everything worked fine, load average was below 0.! Why? :( Now I'm forced to use another distro for this, but I really want to use Fedora Core as the server, because I like it so much and it has many resources. So, anyone here can help me find what's the problem? :( Thanks! []'s Hugo
