NodeBB Global Tchat : Forum with many users performance issues

[DownPW]

@phenomlab

An idea for where to put this code before I open a thread an NodeBB communauty ?

[phenomlab]

@DownPW not specifically, no, as there is an existing function with the same name. The comma at the end of the revised function would indicate part of an existing array but I’m not entirely sure of where it should be placed - or if it should override the existing function altogether (which I don’t think is the case).

@phenomlab arf I hope i have an answers in nodeBB

But it’s an async function maybe here :

[phenomlab]

@DownPW you can always experiment

[DownPW]

@phenomlab no luck

[phenomlab]

@DownPW what have you tried?

[DownPW]

@phenomlab lot of things

[phenomlab]

@DownPW can you provide some brief examples?

nodebb build is ok with this code but I don’t see any diiference of latencies
