in reply to RE: RE (tilly) 3: sort performance
in thread sort performance

I suspected that, but it cannot be because the straight method without that line is much faster, and as you change the $foo line you see the speed of the stupid sort change.

I suspect a more fundamental issue with how map and grep are implemented, and it should IMO be fixable.
