		perlgeek on May 15, 2011 \| parent \| context \| favorite \| on: Perl 5.14 released 20% to 30% has typically been the difference between threaded and non-threaded perl interpreters. Have you checked if both your old and the new perl have the same threading settings? I expected some performance improvements from the upgrade, but I found 20% to be pretty surprising -- still I won't complain :-)

Nope, no useithreads in either of them. We haven't build a threaded perl in ages.

The noted speed improvement is for a hefty Catalyst + DBIC + Moose app. Also seen similar performance improvements in a smaller Dancer app we have. Maybe it's related to the BUFSIZ changes.
