NYTProf split.pl

Profile of split.pl for 53716s (of 54031s), executing 223746982 statements and 66830762 subroutine calls in 130 source files and 40 string evals.

The Flame Graph above is a visualization of the time spent in distinct call stacks. The colors and x-axis position are not meaningful.

You can view a treemap of subroutine exclusive time, grouped by package.
NYTProf also generates call-graph files in Graphviz format: inter-package calls, all inter-subroutine calls (probably too complex to render easily).

You can hover over some table cells and headings to view extra information.
Some table column headings can be clicked on to sort the table by that column.
