Maybe also CPU problem. But except when discourse was running some maintenance jobs, we almost never had any problems with performance before. Just now with profile page, so I was thinking on the last update.
But I should say that before trying revert I also tweaked app.yml:
- For some reason we were having
db_shared_buffers: "128MB", four times less that recommended, probably some legacy from time when I was setting forum first time. I have commented this out, so discourse can setup it himself based on host RAM. - Also I have uncommented
db_work_mem: "40MB"
But I did a proper rebuild and tested this first, and it didn’t help us. Only after revert it became better.
Just now tested again without revert just in case, and I can see 502 on profiles again.
If needed I can do more tests with/without patch.
