Dear whiskers. I just wrote the guide to perform a throughput test against Openwhisk in cwiki. https://cwiki.apache.org/confluence/display/OPENWHISK/Performance+Benchmark
You can easily perform throughput tests with multiple actions and namespaces with it. I hope this would be helpful for those who want to perform stress tests with various scenarios. Please ping me if you have any questions on it. Thanks Regards Dominic.
