--------------------------------------------------------
> Invalid performance breakdown returned for asynchronous aggregates
> ------------------------------------------------------------------
>
> Key: UIMA-4154
> URL: https://issues.apache.org/jira/browse/UIMA-4154
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Eddie Epstein
> Assignee: Richard Eckart de Castilho
> Priority: Major
>
> 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.
