4 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 Origin (uBO) is less resource-intensive than ABP.

Rigorous benchmarks demonstrate that uBO 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 extensions are open
  • 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 extensions has performed a one-time resource-intensive task (updating filter lists, etc.)
  • Not taking into account the number of filters in both extensions
