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

@baris After disabling and uninstalling the plugin the CPU reduced but the It is still very slow when refreshing with logged in user and got 504 timeouts

Evg R

@baris

refreshing the page with logged in user

<baris>

I suggest checking top on your server to figure out if its nodejs or your database causing the cpu usage. And check your database to make sure it has the proper indexes.

Do you have custom code that executes for logged in users?

Evg R

@baris

I use nodebb v14.1 as I remember and I did not do any changes in db after installing.
I do not have custom code. The problem is appeared after installed write-api and posted several ten thousand topics. So when logged in the are always timeouts for now I cant even open /admin - 504 Gateway Time-out

Because I've posted one more bunch of topics using write-api. It looks like something is here related to nodebb-write-api. The more topics I posted the longer time of page loading with logged in user I have.
@julian it looks like you are the author of nodebb-write-api plugin that I've installed and use What can be the problem here and how to fix that? Any ideas?

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?

https://docs.mongodb.com/manual/reference/method/db.collection.getIndexes/

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.

@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?
