  Is a dedicated server mandatory

  Greetings. I successfully (I think) set up ATutor on my home computer (XP, Apache1.3, PHP4)
  
  Elated with my success, I tried in on my web site (Linux Shared hosting). Appears to work, though slowly. My hosting company has the following guidelines for CGI programs:
  
  >>"Please optimize your scripts relative to memory usage and CPU time. Our system automatically stops scripts that use too many system resources."
  
  >>Programming Limits:
  >>CPU : 6 seconds @ 100%
  >>Memory : 10240KB (10MB)
  >>Numerical Processes : 12"
  
  Are there any php scripts which might exceed the 6 second limit?
  
  I had problems connecting with mysql on my XP box: one script timed out at 30 seconds. No problem on the linux share host however.

  Is a dedicated server mandatory?

  Your host specifies CPU : 6 seconds @ 100%, which is different from actually taking up that much time. A script could take 30 seconds while only actually using half that time with the CPU.
  
  Some scripts require considerably longer than 30seconds to complete (such as uploading files or sending out email).
  
  Your host has set those limitations to make it impossible from a single client from hogging all the resources. Although ATutor can function in a shared hosting environment, these restrictions would probably not allow it to use enough resources needed to conduct real courses online.
