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.
