Adaptive Optimization Vs JIT Compilation

883196Oct 14 2011 — edited Oct 18 2011
Hello All
In the below link it is stated that Adaptive Optimization improves the preformance by compiling only frequently used methods.
Now even in JIT compilation I believe there is threshold that is set , like only if a method has been invoked 400 times the JIT compilations will happen. So my understanding is even in JIT compilation only frequently used methods are compiled.
But I know I am certainly missing something here as the link is from Oracle.
Could some one please clarify ? Any insight is higly appreciated.
