increase Thread start performance in java

Question

Is there a way to increase the performance of Thread.start method. as i know Thread.start will call the run method of the tread in a separate thread but i have found that it need time more than simple method call in the calling context.

Answer 1

Starting threads definitely involves overhead. You may want to consider thread pooling.

Answer 2

Thread.start is native. It does a lot more than calling run - it uses Operating System calls to create a thread stack and lots of other things. Consider using a Thread Pool.
