    OpenDemand Systems

  • Over design of Web pages (too many graphics)
  • Bad code (avoid recursive function calls)
  • Web server connection limit too low (IIS is set to 10 by default)
  • Poorly tuned Web application server (play with your Administration Server Settings)
  • Excessive queue lengths (more than one) & wait times (more than a few milliseconds)
  • Memory contention issues (paging in)
  • Heavy disk I/O (high service times)
