MCE also includes wc.pl. I thought why not compare the wc binary with wc.pl.

## wc -l very_huge.file

$ time wc -l very_huge.file
100000001 very_huge.file

real  0m0.781s
user  0m0.521s
sys   0m0.260s

$ time ./MCE-1.608/examples/wc.pl -l very_huge.file
 100000001 very_huge.file

real  0m0.612s
user  0m0.633s
sys   0m1.522s


## wc very_huge.file

$ time wc very_huge.file
 100000001  300000003 2200000015 very_huge.file

real  0m21.621s
user  0m21.341s
sys   0m0.289s

$ time ./MCE-1.608/examples/wc.pl very_huge.file
 100000001 300000003 2200000015 very_huge.file

real  0m6.210s
user  0m23.639s
sys   0m1.034s


## LANG=C wc very_huge.file

$ time LANG=C wc very_huge.file
 100000001  300000003 2200000015 very_huge.file

real  0m6.860s
user  0m6.519s
sys   0m0.344s

$ time LANG=C ./MCE-1.608/examples/wc.pl very_huge.file
 100000001 300000003 2200000015 very_huge.file

real  0m1.973s
