Devel::NYTProf 3.0 is out, more mindblowing than ever

| No Comments

Go run to the announcement about Devel::NYTProf v3.0. Marvel at the code profiling goodness.

Highlights include:

  • Ability to profile opcodes, which means...
  • NYTProf can now profile slow regular expressions
  • More detailed stats on BEGIN blocks
  • Treemap of subroutines
  • Tracking of which subs called which other subs
  • Graphing of sub calls
  • Improved report output
  • Ability to merge profile runs, such as when a process spawns other processes like mod_perl code does.

Already I have found that my regular expression compilation is taking 6% of the runtime in my sample runs in ack. I had no idea.

Just amazing. Go try it now, and buy Tim Bunce and the other contributors a beer.

RJBS Advent Calendar

Ricardo Signes' calendar to showcase things he has been working on. His first entry is about Sub::Exporter which looks very powerful.
