Re: Re: serious regex performance degradation after upgrade to perl 5.8 from 5.6

Soo, to see if just a string 4 times bigger can make the REGEXP 4 times slow

What a load of crap - This has to be seriously one of the worst answers that I have seen posted on this site, dressed up as determinate rationale ...

The OP would be better to following the avenues of investigation offered by other posters, namely, increasing test sample size, employing a better test framework (Benchmark), considering the difference between threaded and unthreaded versions of Perl - the performance difference between threaded and unthreaded versions of Perl can be quite significant, even where threads is not employed - and following up with perl5-porters.

So gmpassos' post was incorrect -- your response however seems unnecessarily aggressive; particularly when posting anonymously care needs to be taken to avoid appearing abusive. The second sentence of gmpassos' message begins by saying that he might be wrong; he offered a suggestion, it might not have been right but there's no reason to believe his intention was anything other than to try to help. edit: fixed tpyo	[reply]
