Ok so basically I have a chat, and it retrieves messages from the database ever 500 miliseconds, now obviously this will run my CPU and hits like nothin. Therefore I would like a method to check whether or not messages have been received in the past 30 secs.

My objective is:

Ok if a message is not sent within say, 30 secs, then the JS only retrieves message every, 20 secs or so; however, if there is back and forth messages, then retrieve every 500 or 1000 milliseconds.

Can anyone give me the logic, I don't need the code… Very much appreciated, because my server is frozen for a few hours, therefore i need a solution lol! I have considered sockets, but I don't know how to implement them.

Should this be server-side?

Perhaps the browser's javascript/Ajax could check the timestamp of the DB's last entry: if it's recent, check again soon; if it's long ago, wait a little before checking again.

This tutorial part 5 of it has a counter to increment a timeout variable, I'm not following it for my code, but would like to implement the logic, can someone please help explain this part. Though this is more of a client side issue. I'm dumb sorry.
