in thread "my" slowing down programs?

Thanks for the information! Indeed when testing with version 5.22 the timing differences are completely gone.

P.S.: my trials to install Devel::NYTProf in strawberry perl 5.22.0.1 (Windows 7) failed (due to some failed tests). Did others make the same experience?
