EDIT to manage expectations: the article doesn't explain why, it just provides benchmarks and one commenter made a suggestion about character handling. More insight still welcome :)

There are many different versions of awk: gawk, (BSD) nawk, mawk, etc. I think OS X uses nawk, but mawk is reputedly faster. Gawk is definitely slower than both mawk. I'm not surprised that Perl is faster though.
