The machine is a Gateway 955 Xeon 1.7Ghz, 3Gigs of Ram. I think it maxes out at about 25 concurrent. In one class I have about 35 and it slows to a crawl.
In this room I have rather new, 2G RAM, DualProcessor workstations. So what I wanted to do was to do a share-nothing but rsynced moodle and a replicated mysql on all the workstations behind a load balancer (like Hercules). This is not a lot of work since we have Altiris to manage images on workstations. The workstations just need to run all the time..
Myles.. Thanks.. In any case I will try the performance tune-ups first.
