# New Ticket Created by Angel Faus # Please include the string: [perl #15425] # in the subject line of all future correspondence about this issue. # <URL: http://rt.perl.org/rt2/Ticket/Display.html?id=15425 > Hi, This patch does the following things: - it includes patch #15358, that tries to make the regex engine GC-safe - it fixes a bug on the rx engine, that caused the Intstack on rxinfo not to be ever freed. As a result of this bugfix, very simple regular expressions get a noticable speed-up. For example, this is the data of matching the pattern /^zza/ against "zzabbbbbbbbbcdcdcdcdzz" 100.000 times, with the loop inside parrot (or perl5) parrot, without the patch 12.834 seconds parrot, with the patch 1.216 seconds perl 5 0.21 seconds This is of course not representative data, the speed-up is much smaller for the average regex. -àngel -- attachment 1 ------------------------------------------------------ url: http://rt.perl.org/rt2/attach/31153/26111/ffdaea/perlreinfo.pmc -- attachment 2 ------------------------------------------------------ url: http://rt.perl.org/rt2/attach/31153/26112/cf3c94/rx_patch.diffThread Next
