@pitaj So far I haven't been able to test the traffic spikes as I haven't had any lately
I did found a typo in my nginx file which I've fixed already and it seems to run better. I'll report back as soon as I get more data.
use nodebb-plugin-write-api and you can create how many post you like using ajax instead socket.io
PS: creating your own posts doesn't mean your site will be any good. It will look "not poor", but it will be anyway.
