Hello all, after the first embarrassing numbers of the Golang runtime that made me hurry to fix performances :)), here I provide the updated numbers of action-loop based runtimes compared with the current ones. Those numbers can vary slightly from one run to another (for example I discovered it depends how charged is your Mac) but generally are proportional when running in the same environment.
I just run the benchmarks, and I have: Performance report *** actionloop-golang-v1.11 (improved) Requests/sec: 1086.67 Transfer/sec: 154.93KB *** nodejs6action Requests/sec: 1006.41 Transfer/sec: 225.07KB *** actionloop-nodejs6action Requests/sec: 1230.92 Transfer/sec: 157.09KB *** python3action Requests/sec: 20.05 Transfer/sec: 2.62KB *** actionloop-python Requests/sec: 1066.84 Transfer/sec: 139.61KB Note the actionloop runtimes are really prototypes, I have not run any test suite against them. -- Michele Sciabarra mich...@sciabarra.com ----- Original message ----- From: Michele Sciabarra <mich...@sciabarra.com> To: dev@openwhisk.apache.org Subject: Submitted PR for performance boost of the Go Runtime Date: Tue, 27 Nov 2018 23:38:11 +0100 I just submitted a PR to improve performances of the Go/ActionLoop runtime while being the less invasive possible. I am keeping the current design and I have not changed approach: there is still child process fed by the HTTP server on standard input with output on file descriptor 3. I am still using the standard http server (not the fast HTTP server). On the converse, I removed all the goroutines. They do not play well with external processes. Instead, I am using the classical technique of suspending on reading the standard input is fast to commute to the child process/ I reached in my tests around 1150 requests/second (a bit worse than the nodejs but I think decent). It is possible to further improve performances up to 1500 but I need to abandon the actionloop model and run an action with an independent server, so for now I am not doing anything like this, -- Michele Sciabarra mich...@sciabarra.com
