help with networking and threads
is there anyway to make this implementation more efficient?
The implementation is:
There is this method thread that has an infinite loop which waits for connections and accepts it if there's one. The implementation is hungry of CPU usage. is there anyway to slow down the CPU usage? like setting up a timeout for the infinite loop, etc. (i'm not quite sure about the timeout thing)

Normally it can be happened, because of the loop. I can't say more about without having exact idea what your application do.

ahh. i see.
well, we are currently making a customized Server-Client instant messenger. and the server (the one that handles connections) is the one that has the infinite loop waiting for connections. is there anyway to lessen the CPU usage by any other means?

Rather using an infinite loop, can you make a request from the client in specific intervals? In that case, only the requesting time CPU usage is high.
Is that server written in Java?

would having an infinite loop that sleeps at specified intervals achieve the same result that you have described?.. im assuming the cpu usage would lessen when the thread sleeps (timeouts)...

Yep it should be, if the thread sleep CPU usage should be lesser. Didi you use more than one thread, if so how did you handle them?

I don't think 10 millisecond is enough. Can't you do it at least within 1 second. And also, did you synchronized any of thread.
