Myth: uBlock is just slightly less resource intensive than Adblock Plus

No: it is significantly less resource intensive than Adblock Plus ("ABP").

Sloppy benchmarks can lead to the myth that uBlock is just a tad less resource intensive than ABP.

Rigorous benchmarks demonstrate that uBlock is significantly more efficient than ABP.

Examples of sloppiness:

• Using memory footprint figures before the browser's garbage collector kicks in
• Not taking measures to avoid tainting memory footprint with Chromium bug 441500
• Using memory footprint figures while option pages for one of the extension are opened
• Disregarding the contributed memory footprint to web pages
• Comparing memory footprint after extensions have run for a significantly different amount of time
• Using memory footprint figures after one of the extension has performed a one-time resource-intensive task (updating filter lists, etc.)
• Not taking into account the amount of filters in both extensions
