Socket.io .on(message) seems be delayed
0
I have server code like (simplified)
setInterval(longFunction,30);
setInterval(longFunction,30);
function longFunction(){
console.log("longFunction");
doSomethingLong();
}
elsewhere in server code...
socket.on("message",function(){
console.log("message");
})
Problem is that when I send message from client, I can see in server console many many new logs from longFunction and only then I can see log from message.
I want to process message event as soon as possible but it looks that server prefer processing of intervals even multiple times first.

because thosesetIntervalare running in30msinterval even beforedoSomethingLongis done, effectively queueing the CPU for multiple times before any socket message can reach and be processed by server?

It depends on what your expected behaviour betweensetInterval,longFunction, and weksocket is, need more context.

I want more priority for message event. If I have message event, process it and run timers later. I changed setInterval to setTimeout and it didn't help. Problem is probably that i have more timers so they run in loop and no other code can be executed.

Since javascript is single thread, ifdoSomethingLongis a long running sync function, it cannot be pause/broken in the middle of execution. However what you can od is check if any message event should be processed before runningdoSomethingLong, i.e. in where yourconsole.log("longFunction");is now.
