Memory Problems

To check available memory on a machine:

Open the Task Manager. Select the Performance tab to check the physical memory available. Select the Processes tab to check which processes have high memory consumption in the CPU column.

To increase the amount of free memory:

  • Close any unnecessary processes running on the machine, and try running the scenario again.
  • Restart your computer.
  • If the problem persists, reduce the number of virtual users that you are running on the same machine.

To enlarge the size of your virtual memory:

  1. Click Start > Settings > Control Panel > System.
    • For Windows 2000, select the Advanced tab, and click Performance Options.
    • For Windows NT, select the Performance tab.
  2. In the Virtual Memory section, click Change.
  3. In the Drive list, click the drive that contains the paging file you want to change.
  4. Under Paging file size for selected drive, type a new paging file size in megabytes in the Maximum size (MB) box, and then click Set.

To boost performance, and allow more Virtual Users to run on the load generator machine:

  • On Windows 2000 machines, select Start > Settings > Control Panel > System > Advanced > Performance Options, and select the Background Services option.
  • On Windows NT machines, select Start > Settings > Control Panel > System Properties > Application Performance. Set Performance boost to "None."
