The main file that needs review is:

chrome/test/functional/perf.py

The other files comprise a webpage used by the new test, and its associated
files:

chrome/test/data/scroll/plus.html
chrome/test/data/scroll/plus_files/*

I didn't realize I had introduced a slight problem with some <pre> data at the
bottom of the file.  Would you be so kind to get the current version of
plus.html from semenzato/?

Otherwise LGTM.

Thank you both for the review!  I retrieved the latest plus.html file as
