Description

The DuccRawText sample application runs with a synchronous aggregate replicated in 8 threads. The performance breakdown closely matches the breakdown when the application is run in single threaded mode (all_in_one).

If the JobProcess is submitted as an async aggregate (as a DD job) with one CM, eight AE's and one CC, the performance breakdown is clearly invalid. For example, in sync mode the CM is less than 0.1% of total CPU, but in async mode the breakdown shows the CM with 66% of total.
