RocketChat 7 slow API responses with default docker deployment

michal.mocnak · February 13, 2025, 5:01pm

Description

Default docker deployment with rocker.server v7 (7.2.2 and 7.3.1 tested) is super slow on each API request = approx 7-12 seconds to response.
Checked same configuration on v6 and it does work properly without any issue.

You’ll have to tell us what you are actually trying to do.

What API calls?

michal.mocnak · February 13, 2025, 9:53pm

I am sorry. Literally every single API call is that slow. Checking via Chrome debug tools.

michal.mocnak · February 14, 2025, 9:09am

For example endpoint /api/v1/settings.public took 5.76s in v7.3.1 but in v6.13 it took 10ms

reetp · February 14, 2025, 6:22pm

What do your server logs tell you is going on?

What file storage are you using?

michal.mocnak · February 15, 2025, 7:51am

Nothing wrong in logs seems to me and storage is now local SSD.

Are you using GridFS or “local storage”?

Check your collection sizes too.

michal.mocnak · February 15, 2025, 1:30pm

It seems i figured it out. I am using just local storage. Later i’ll switch into MinIO. I realized mongodb was in traefik_proxy network instead of chat_internal. As rocketchat service is in both but chat_internal has as the main. Probably in v7 there is different dns resolve or something like that and it timeouts resolving mongo in different network.

However in v6 it worked well. And what is strange too is when i have set networks correctly and switched to mongo 7 it started to be slow again ;o)

Anyway now i am running mongo v6 and rocketchat v7 and it works well!!

reetp · February 15, 2025, 6:34pm

This I guess?

Glad you got it sorted.

michal.mocnak · February 15, 2025, 7:10pm

Actually this was ok but mongodb was in traefik_proxy instead of chat_internal. That was the problem. Why it has problem with mongo v7 i still don’t know. But it works with v6 so i’ll leave it ;o)

reetp · February 15, 2025, 7:23pm

Kk.

I’d start figuring the upgrade. You’ll have to eventually!!

michal.mocnak · February 16, 2025, 5:03pm

And finally i’ve figured it out with mongo version. All the problems were connected to the os version. Initially i’ve tested it on Ubuntu 22.04 LTS and it seems after upgrading to 24.04 LTS it starts to work correctly. Probably it was connected to mongo and it’s dependencies (even 22.04 is offically supported for version 7).

reetp · February 16, 2025, 6:21pm

That’s a ballache but excellent feedback thanks.

Typical with this fangled rapid release, beta at best, who cares if we didn’t test throroughly nonsense…

Not good enough at Enterprise level IMHO.

It will get mentioned
