Total method time in Java VisualVM

Question

In Java VisualVM, is there any way to display total method time, rather than \"self time\"? (The latter is not particularly useful, since it doesn\'t tell you anything about

Answer 1

There's a simple way to get total time of a routine as a percent of wall-clock execution time (rather than milliseconds). Just use ctrl-break to get a bunch of stackshots while you're waiting for it. The fraction of them containing the routine is the % of time it takes. The accuracy depends on how many shots you take. If you're just looking for where the problems are, you don't need precision time measurement. Here's a short explanation of how it works.
