NAME Runops::Switch - Alternate runloop for the perl interpreter SYNOPSIS perl -MRunops::Switch foo.pl DESCRIPTION This module provides an alternate runops loop. It's based on a large switch statement, instead of function pointer calls like the regular perl one (in run.c in the perl source code.) I wrote it for benchmarking purposes. As dynamic extension there is no notable speedup measurable. 516 non-threaded: $ ./TEST op/*.t u=0.46 s=0.06 cu=16.27 cs=0.95 scripts=182 tests=47170 $ PERL5OPT_TEST=-MRunops::Switch ./TEST op/.t u=0.49 s=0.02 cu=16.39 cs=0.83 scripts=182 tests=47170 (dynamic_ext overhead) KNOWN PROBLEMS This module calls directly the "pp_*" functions from the Perl interpreter (not through a function pointer). Since those functions aren't part of the public Perl API, they won't be available unless you happen to run an OS that exports every symbol by default (such as Linux without "PERL_DL_NONLAZY" set). Notably, this module does not compile on Windows. AUTHOR Written by Rafael Garcia-Suarez, based on an idea that Nicholas Clark had while watching a talk by Leopold Toetsch.
