I have noticed that the async task executor can be enhanced by removing some thread sleep in class like AcquireAsyncJobsDueRunnable or AcquireTimerJobsRunnable.
I have already submit this enhancement some times ago (activiti version 5.0.17.), I use to test with the protocol described in this post (http://www.jorambarrez.be/blog/2016/07/20/message-queue-async-executor-benchmark/)
With the last version of activiti (7-201709-EA), I'm encoutering some issues while unacquiring job.
I there a new project to benchmark async tasks execution ?
