CPU%.

The percentage of CPU usage includes other external tasks running on the system.

Memory usage.

The percentage of memory usage includes other external tasks running on the system. If the memory usage is close to 95%, check if the tasks running on the system are using the amount indicated in the Workflow Monitor or if there is a memory leak. To troubleshoot, use system tools to check the memory usage before and after running the session and then compare the results to the memory usage while running the session.

Swap usage.

Swap usage is a result of paging due to possible memory leaks or a high number of concurrent tasks.
