• If the schedule, in this context, is used to refer to VU Schedule and Rate Schedule contains loops, move the loops into tests. If a schedule, in this context, is used to refer to VU Schedule and Rate Schedule contains loops, at the beginning of a loop iteration each virtual user closes existing connections and opens new connections. This can cause the agent computer to exhaust all available TCP/IP ports. If a test contains loops, virtual users attempt to re-use existing connections. Re-use of existing connections can take advantage of keep-alive connections.
• Increase the number of TCP/IP ports available. The number of TCP/IP ports on a Windows™ computer is limited to 5000 by default. To increase the number of TCP/IP ports available on a Windows™ computer:
  1. Create the following Registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort. This key does not exist by default.
  2. Specify the type as DWORD.
  3. Set the value to 65000.
  4. Reboot the computer.
