How Fast is Running Perl in Cygwin or Using NTFS on Linux? (The Price You Pay for Layers and Emulations)


Here's a speed comparison of running a Perl script on Microsoft Windows vs Linux, using native vs non-native port, and using native vs non-native file system.


Tech Detail

The Perl script validates local links of HTML files. The script goes over 8.2k HTML files. Files that don't end in “.html” are skipped by regex. (there are a total of 23.3k files. 3.1 Giga bytes (lots image files))
