@TheBronx
I do agree you very much that the polling requests are causing an enormous load on the server. My machine is powerful enough holding 65000+user and 140000+ posts.
But the load is heavy at peak time, and if I restart nodebb, it can not even recover until the peak was passed.
@administrators
Any idea on this? I was obsessed with this for long...
I found that the ESTABLISHED connections are too large. Does that count for this issue?
No matter peak time or valley time, this number almost seems the same.
