-----------------------------------
Summary: 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
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.
