Can anyone tell me when the most appropriate times are or would be for embedding C code into Perl code? (ex. is a hash in C going to be faster than Perl?) I don't currently have any C code written for any of my projects but I am looking for a way to increase the speed of my Perl scripts, so what would be the best utilization for speed with C embedded in Perl? Is looping through an array in C really going to be any faster in C than Perl???
