Very long page loading time when refreshing and I am logged in by any user and quick loading when I am logged out

Evg R

@pitaj The problem appeared after I installed nodebb-write-api plugin and post several tens of thousands topics, the more topics I posted the longer time for refreshing the page with logged in user

So I do not think other plugins rather then nodebb-write-api impact this issue

PitaJ

@evg-r okay well try disabling various plugins anyways. You don't need to keep write API active after you're finished using it to create the posts.

If disabling plugins doesn't work, then I think you should try upgrading to the latest version of NodeBB, 1.18.6

Does this happen if you create a new user and login with that? Wonder if it has something to do with a user having tens of thousands of topics made in the same day.

@baris I've just tried with newly created user and it's the same situation - timeouts

@pitaj

I've disabled all the plugins - CPU is becoming lower but I still have timeouts when log in and refresh (almost all the time > 1min, sometimes 58secs)

Evg R

Today the page load time is about 5-10 secs for logged in user (previously it was more then 1min), so maybe some sessions are destroyed or something?

I kept write-api-plugin disabled and did not use it for 2 days

PitaJ

I'd bet it just took some time for the indices to rebuild.

@pitaj I've just checked the indexes in db, and find out that nodebb db size is 0. So I forgot that I store all the data for nodebb forum in the different one db, and that db already had the indexes. So no changes were made to the db with nodebb forum
The reason of long load page time is still mystery but its related somehow to write-api plugin.
I need to use this plugin to post more topics but I need to fix something to avoid such bad situation with long load page time

PitaJ

@evg-r I doubt it's anything to do with the write API plugin. If you want to avoid it though, you can use the built in write API in newer versions of NodeBB.

I suggest:

Use the latest version of NodeBB (1.18.6)
Use the built in write API
Post your topics, then wait a while for the database indices to build in the background

Evg R

@pitaj But when I log out the speed is quick as usual. Could it be related to the indexes with such a behavior?

julian

@evg-r Not really, no... but you never know.

What happens if you disable the write API temporarily and rebuild/restart NodeBB? Do the topics load quickly then?

If not, then you can safely rule out the write API plugin.

Evg R

@julian When disabling the plugin and rebuild the Speed is the same. But day by day of just waiting it becomes quicker since the last creation day of topics

julian

@evg-r Right, so it is not related to the Write API plugin then. The evidence still seems to point to a plugin causing issues with loading NodeBB content.

@julian @PitaJ It looks like when I am logged in it selects additional not indexes tables. We need to improve, make faster queries of the newly added topics. Can you suggest more indexes exactly for logged in user?

Evg R

@baris creation of index for tid can help in this case? can it harm something?
what additional indexes would you suggest to add?
