Orion content blockers are automatically 'Off' for browser benchmark sites. They test really fast with it off as-is, but forcing them on causes drastically worse numbers on the benchmarks. While I was expecting a slight decrease in performance, the difference was drastic; even third-party adblock extensions do not decrease performance by that much.

Here I did 3 tests on Speedometer 3.0:

  1. With content blocker OFF (and compatibility mode ON)
  2. With content blocker turned ON for that site (adblock extension disabled)
  3. With content blocker OFF and uBlock Origin ON

Compatibility Mode

Content Blocker forced ON

uBlock ON

Can this result be a contrapositive indication that Orion's native content blocker is making all JS webpages perform poorly?
Does Orion's content blocker work on a lower level compared to uBlock? Or does it just work off a blocklist?

*I brought this up on discord but I am posting it here too to make it official.

I expected benchmark numbers closer in parity to the test I got with the uBlock extension on.

    galacticmice Thats not supposed to happen, as I guess the content blocker parsing needs kind of optimization.

    Few questions:

    1. Are you using default lists only? or you have enabled or added some other filter lists?
    2. Can you please try same with a clean profile and let us know if it's all same or not? (no extensions and only Orion's content blocker)

        I tried the same with a clean profile and default settings:

        Found the culprit, Fanboy Annoyance List seems to be the one dropping performance by a lot even with a clean profile. For my regular profile, I disabled it and performance went back up to 27. Still not as good as uBlock(with a lot of lists turned on), but better nonetheless.
