Bad performance due to sleep() in AcquireJobsCmd

keymaster — Tue, 01 Mar 2016 12:11:56 GMT

The sleep(100) inhttps://github.com/Activiti/Activiti/blob/master/modules/activiti-engine/src/main/java/org/activiti/engine/impl/cmd/AcquireJobsCmd.java#L58caused a significant performance reduction. Should I create an issue?

Did you try the async executor? It does not have that sleep method and performs better (for various other reasons).

This currently is no option for our project, sorry. The Application is tested and staged for production.

We removed that sleep. The question is, if you want to fix that for other projects. A sleep in that method smells like a bug or a race condition.

No, because that sleep was probably introduced for a reason and it'll break other things.
We've created the Async Executor, which has proved to be far superior when it comes to performance. The old job executor will be deprecated in the future.
