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

[julian]

@evg-r can you try the built in write API instead of the write API plugin?

[Evg R]

@julian As I know build in write api is implemented in nodebb v15 and above. But I have nodebb v14, so need to install plugin. Do you know this issue what should I do to fix? For now I cant even login by any user I have always 504 timeouts after 1min of loading

[julian]

@evg-r I echo @baris' question:

Does your database have the proper indexes?

[Evg R]

@julian which collections should I check?

[baris]

objects collection

[Evg R]

@baris

it looks like no indexes

[baris]

@evg-r Create them with these commands

db.objects.createIndex({ _key: 1, score: -1 }, { background: true });
db.objects.createIndex({ _key: 1, value: -1 }, { background: true, unique: true, sparse: true });
db.objects.createIndex({ expireAt: 1 }, { expireAfterSeconds: 0, background: true });

[Evg R]

@baris

done and what next?

[baris]

Restart your forum and see if it's faster now.

[Evg R]

@baris No, I still have this problem

[Evg R]

@baris any other suggestions?

[baris]

Next thing to check would be network usage and how many users are accessing the forum. If it is only your user then you should check out the custom code you have and see if there is anything wrong there.

[Evg R]

@baris what tool do you advise to analyze a network usage?
I do not have my custom code only plugins

[Evg R]

@baris The problem with 504 timeouts appears only when I try to login or refresh with logged in user. Maybe some cache for sessions should be cleared or something related to user data?

[PitaJ]

Have you tried disabling various plugins?

[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

[baris]

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.

[Evg R]

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