Java performance issues -


i'm in process of benchmarking app i've written. ran app through benchmark 10 times in loop (to 10 results instead of 1). each time, first iteration seems take 50 - 100 milliseconds longer rest of iterations.

is related jit compiler , there 1 "reset" state initial "lag" included iterations?

it caused jit kicking in, want ignore initial lag anyway. @ least benchmarks try to, because heavily distorts statistics.

you can't "uncompile" code has been compiled can turn compiling off using -xint command line switch.
