Why is the test mean time for a page greater than the total mean?
The totals line only includes data from basic tests, i.e. tests that do not include other tests. It does not include the data from composite tests, i.e. tests that include other tests, such as those those wrapping pages in HTTP scripts generated by the TCPProxy. The time taken by these page tests is typically quite long since it also includes sleep time and can easily exceed the average time for basic tests. Composite test lines in the Results tab have a grey background to emphasise that they are different. This is done so that the totals line is meaningful, useful, and understandable. If data from composite tests were included in the totals line, some of the values (e.g. average test time) would be meaningless since time would be accounted for twice, once by the basic request tests, and once by the page test that wrapped the requests. Data from composite tests is also not included in the totals line in the worker process output log files.
