using wait - does this affect system performance? <---- gurus please

Hi,

we use wait (5000) a lot in our threaded systems. (we have our own object queues)

in jprofiler this comes up as a hotspot - this is not a bottle neck though right?

thanks

I'm not a guru, but I don't see how this could affect performance ... unless you get stuck with a lot of threads in the waiting pool. Even then, they get released in about 5000 miliseconds.

(I feel this question is more appropriate for our performance forum)

Its very hard to point out whether it is a bottleneck or not unless you give us a clue about where it is used.
A simple i++ can also become a performance bottleneck if you do it a million times in the code path. In such a case, it will not be that i++ is non-performant but it is the code that uses it, is the problem.

For example if you have this wait for threads in a receiver thread pool in a server, you might as well looking at very low throughputs. So, without the context/code it is very hard to tell whether it actually is a problem or not.

It is just a wild guess, but it might be so, that your profiler prefers a call to wait() over a call to wait(timeout).
