+### AsciiDoctor Benchmark and git branch performance comparison
+
+It is testing the performance for the real life application AsciiDoctor, compiling it, running it and asset size.
+It prints a nice summary to compare the current branch with the master branch.
+On Windows make sure to have the Ruby DevKit enabled with `ridk enable`.
+
+Run the task on any system with: `bundle exec rake performance:compare`
+
+Example output:
+```
+=== Summary ===
+Summary of performance changes between (previous) master and (current) v1.5.1-48-gc470e969:

+Comparison of the Asciidoctor (a real-life Opal application) compile and run:
