Java performance multi-core testing environment

I am interested in learning as much as i can about tuning a multi-threaded java server on a multi-core machine. I wanted to write some test servers that i could use to test different scenarios. For example thread pool sizing. Unfortunately i don't have access to a large multi-core unix (linux or solaris) machine. I just have duo-c开发者_StackOverflowore mac laptop.

Are there any good lease options for a dedicated, say 8 to 16 core machine, that i could distribute my java test servers?

Get an Amazon EC2 Quadruple Extra Large (u$d 1.60 per hour). It is a dual quad core computer, and each core can run 2 threads, so you get a total of 16 threads.
