Add performance testing script to mshots

roo2 commented 2 years ago

We have plans which will put a significantly increased load on mshots, I'm adding these scripts to test whether mshots is up to the task and also to have a way to test future performance improvements.

I went with a python script using the locust framework because we've used python for one off things around wpcom and I think the framework is quite nice.

Test instructions

Follow instructions in scripts/performance-testing/README.md and ensure that they capture everything that needs to be done on your machine.

Maybe I'm missing something, but it's hard to see if locust is running the test as intended. Could you upload screenshots/recordings of what a successfully test looks like?

you have to run locust and then open a browser at http://localhost:8089/ locust docs

I added some screenshots to pbxlJb-1sw-p2#how-many-new-preview-requests-per-second-can-mshots-handle you have to go to the "Charts" tab e.g.

Automattic / mShots
