Hello marioroy,

It's impressiv ! And i've test successfully your code. Eventually the Strawberry dist works the best on my system.

"It's works even well with the mixed file (multiple kind of EOF) ! Benchmarking both the 3 methods, i've found 32,53 and 33,07 for the two codes provided kindfully. My current code (works only on a cr+lf or lf file) have done 33,76".

It's impressive to see the 8 CPU cores up to 100% at the same time with your demo ! But the results only slightly differs with my code which doesn't impact all the core at all like that. Strange !

Very happy anyway, i'm now close to the best performance i could got on my laptop with perl !
