I am a student in the American University in Bulgaria and am currently involved in the .LRN integration process. Our "server" or lets call it test PC is a P4 at 1.3GHz with 256MB RAM. Currently there are somewhere between 180 and 200 active users and this number is expected to grow to 600 at least in a couple of months. Does anyone have recommendations on hardware upgrades so that the system is stable (I know its the RAM but anyways I need a confirmation). And also would you recommend some real server configuration that will allow this amount of users to safely and enjoyably use the DotLRN platform.
