Re^4: string pattern match, limited to first 1000 characters?

It looks from your code that, apart from Fregex and Rregex, your subroutine pairs are identical as you haven't swapped the 'sgml' and 'html' around. When I run your code with them swapped around I get these results. (Rates are slow as the machine is a quite elderly SPARC.)

length of search string: 20904
           Rate Rregex  Fregex  Rsubstr  Rindex Fsubstr Findex 
Rregex  11708/s      --    -16%    -41%    -45%    -61%    -70%
Fregex  14005/s     20%      --    -29%    -35%    -54%    -64%
Rsubstr 19721/s     68%     41%      --     -8%    -35%    -50%
Rindex  21423/s     83%     53%      9%      --    -29%    -45%
Fsubstr 30362/s    159%    117%     54%     42%      --    -22%

johngg: D'oh!++ and I thought I had. I wonder what I was thinking? I know I changed the lines, but I guess I changed 'sgml' to 'sgml' and 'html' to 'html'... (Or did I change it twice during my confusion? I guess we'll never know.) Thanks for catching that! ...roboticus	[reply]
