The harness can run tests concurrently. If you are running the tests on a multi-processor computer, concurrency can speed up your test runs. For your first test run you should leave this field set to "1". After you have the tests running properly you can experiment with this value.

To prevent a stalled test from stopping a test run, most test suites use a timeout limit. The timeout limit is the amount of time that the harness waits for a test to complete before moving on to the next test. Each test's timeout limit is multiplied by the time factor value. For example, if you specify a value of "2", the timeout limit for tests with a 10 minute limit becomes 20 minutes. Try running with a time factor of "1.0" and increase the value as necessary.
