• The test pages are available here: DragonFly, MySQL

This numbers are the basis to claim that dillo2 uses half the memory footprint of dillo1. Just check the last row or compare the factor.

The "factor" is calculated with the RSS for the MySQL manual (with no images), minus the empty RSS, minus 13MB, all divided by 13MB. The memory-cached page is subtracted to get a clean HTML-to-Widgets factor.

This is, if you have a 130KB html page, factor*130KB will be used for rendering.
