I have a Java multi thread application running in a multi core CPU linux box. Ideally, multi thread would distribute load to different core of CPU. What about if I have singleton, concurrentHashmap, atomicInteger in the application, Would that influence performance? So the load would be decreased since the speed would not that fast as totally concurrently?

Are you saying your using a concurrent Hashmap with the singleton design pattern? I dont think you'd need to worry about synchronization when accessing the hashmap because it should be initialized and then would be static. The only synchronization that you would have to worry about is the atomicInteger. The operating system would then handle the work load distribution for the threads.

actually atomicinteger is also fast when there are not too many threads.
