new containerpool performance
Hi Markus -
I found the issue with slow throughput performance I was seeing in the
new-containerpool branch of your fork, I created a PR in a separate fork
here, not sure of a good way to do a PR back to your fork (multiple forks
etc), but the change is pretty minor - just delay some time before making a
container eligible for removal (when scheduling a "free" container fails)
https://github.com/tysonnorris/openwhisk-new-containerpool/pull/1
Test results below are based on new-containerpool branch + this change,
compared to master. Approximately double throughput. To be clear this is
*without* concurrent execution of actions, which I would still like to look
into a bit further.
Thanks
Tyson
