BPM TaskQueryService QueryTasks API is slow when a large number of results are returned (Doc ID 1922798.1)

Last updated on DECEMBER 04, 2017

Applies to:

Oracle Business Process Management Suite - Version 11.1.1.7.0 to 11.1.1.7.0 [Release 11gR1]
Information in this document applies to any platform.

Goal

Very slow performance when querying a large number of tasks via the API.

For instance:
- querying when result set is zero or one task typically takes 60ms-200ms
- querying when result set is 100+ tasks is >5 seconds
- querying when result set is 200 tasks is 7-15 seconds
- querying when result set is 800+ tasks is up to 60 seconds

These timings are all taken from calls to the ITaskQueryService.queryTasks() function.
