In fact, traceview seems to report IDENTICAL times absolutely too, which is strange, because if I use SystemClock.uptimeMillis() for measurent, then I get higher values. And REALITY shows too that methods take more time. But traceview reports contain same absolute values --- I guess because traceview already reduces FPS, so the results are not credible as absolute values. And as percents, they are the same.
