The crux if java performance problems comes not from its raw number crunching abilities (it stands agains c++ in micro benchmarks) but its style of memory mamagement. Moreover JIT has its own memory overhead (runtime performance metrics, heaily instrumented code). Managing memory in pressured conditions takes time, not being able to share heavy runtime between processes adds to it.
Having jit take care of branch optimization also made priogrammers prefer more dynamic style (virtual by default). If they used it in C++ (with GC) the resulting runtime performance would be worse.
Is summ practical java lower performance is a price paid for programmers convenience more than inherent platform flaw.
