See x.com/BrendanEich/status/196… and note we work to compete. More adblock-rs mem savings coming (cc: @shivan_kaul on status of work). By blocking so many scripts, we save a lot of mem once you are up with multiple pages loaded in tabs.
A simple site like example.com takes ~20 MB as expected.
NTP in Chrome and Brave is not as simple, we've observed fluctuation between 60-190 MB.
Brave's perf team is on the case, raised question of whether anyone here used Brave News (below the fold private reader)?
1st part of adblock-rust memory saving work (using flatbuffers for efficient internal data storage) is already in Brave Release: x.com/brave/status/193571628….
Getting ready to merge 2nd part (44% further decrease in mem usage) into Nightly next week🤞should reach Release early Dec.
Brave is getting a performance boost!
The team has overhauled our browser’s adblock engine to reduce memory usage and speed up browsing, especially on older devices.
The change is now on @BraveNightly and should be in the release build on all platforms by August.
Aaaand we're live. The second phase of performance improvements for our Rust-based 🦀 adblock engine already in Beta, coming to Release in December.
Another performance boost is coming to Brave! 🎉
We’ve completed the next stage of improving the memory usage of the browser’s native adblock engine.
Here’s how we’re making your browsing faster…
