I read JIT compiler can improve performance. But I have never used it. Do people really use JIT Compiler?

The JIT compiler is part of the JVM. Unless you take specific steps to turn it off (in which case execution speed will be MUCH slower) you're always using it.
 
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
