Recommendations for performance?

[justyns]

Does anyone have any tips on improving the performance of Kanboard, or more specifically figuring out why it is slow? I'm not sure what the problem is, but it feels really sluggish. Something like clicking on a subtask takes 3-5 seconds for it to mark it as in progress. Navigating between pages or moving tasks on a board also takes several seconds.

I'm using the official kanboard/kanboard:v1.2.35 docker image, and mysql (mariadb:10.11.6-jammy). I have tuned the mariadb config a little bit, mostly based off of mysqltuner. Both kanboard and mysql have 2gb ram each, and kanboard is the only thing using this instance of mysql. The cpu doesn't seem to be getting much use.

I originally thought my issue might be due to a slow filesystem (mounted over a network share), but I migrated the files to a local ssd and it didn't really change much.

The official docker image looks like it already uses php opcache. Is there anything else I should be looking at?
