Your benchmark doesn't specify which implementation of Awk you're testing, and which version of it. Your code is verbose: length($0) shortens to just length: awk 'length > max { max = length } END { print max }' The Perl seems to have an off-by-one error.

  The Perl version counted the newline char, hence the difference.

  It was an Oracle Linux 6 (64 bits) with GNU Awk 3.1.7 and Perl 5.10.1.
