* How fast is Cygwin Perl compared with AS Perl?

well, you can find an extensive comparison here: AS Perl and Cygwin Perl.

Cygperl is overall 26% slower and uses 18% more memory, but there are some noticeable points:

• Cygperl does have an enormous startup cost compared to AS Perl (cfr. hello)
• Cygperl seems to be faster when there's STDIN input to process (cfr. moments, spellcheck, sumcol, wc).
• on the echo test, which involves fork and sockets, Cygperl took 100 seconds with 10000 connections, while AS Perl took less than 2 seconds!
• if we exclude hello and strcat (for which there's a difference of only 0.09 seconds, but which makes more than 100% slower), Cygperl is 0.94% faster than AS Perl.

cheers,
Aldo
