: Have your privacy cake and consume the web too
Brave Software has reworked its browser's Rust-based adblock engine to make it significantly more memory efficient and perhaps more secure. So you get fewer ads now with fewer MB of RAM. According to Shivan Kaul Sahib, VP of privacy and security for Brave, company software engineers have been able to reduce memory consumption by around 75 percent since the reengineering began last year.
"The upgrade represents roughly 45 MB of memory savings for the Brave browser on every platform by default, and scales even higher for users with additional adblocking lists enabled," said Sahib in The benefits of reduced memory consumption include improved battery life and smoother multitasking, while also leaving more memory for other applications., memory usage went from 119 MB to 108 MB. Presently, Brave puts its browser's memory footprint at 104 MB inexamined Brave version 1.85.118 under macOS Tahoe , the browser memory footprint upon reinstallation showed 121 MB in the built-in Task Manager. After fiddling with settings to ensure the browser's Leo AI assistant was completely disabled and restarting, the footprint dropped to 106 MB. We note, however, that Brave's own screenshot shows an increase in the memory footprint of the GPU process, from 52.2 MB to 81.9 MB between the two versions being compared.in an email."Such fluctuations in browser resource consumption across browser runs are extremely common; even the screenshot doesn't show exactly 45 MB of memory reduction, it actually shows a bigger decrease! "Performance measurement is heavily dependent on statistical averaging across multiple runs and we don't have any evidence of a GPU footprint regression internally.", a cross-platform serialization library initially created by Google for game development. It allows access to serialized data without unpacking or parsing – extra steps that add overhead. "This architectural transition allowed us to move the roughly 100,000 adblock filters shipped by default from standard, heap-allocated Rust data structures into a specialized, zero-copy binary format," explained Sahib in his post.stack-allocated vectors "The upshot is that blocking ads and trackers significantly improves user experience around page loading since fewer resources have to be downloaded," he said."Brave has also builtBeyond the performance improvements, Rust has helped make Brave more secure. "Rust makes entire classes of security and reliability bugs impossible," said Sahib."Chromium follows a Rule of Two for safely handling untrusted input from the Internet, and using a memory-safe language like Rust is a great way to increase trust in the safety of the browser." Brave is not alone in its affinity for Rust code, popular these days because it manages to perform well while offering memory safety guarantees. Mozilla, where Rust was created, has implemented in exchange for the absence of sponsored images, Brave Rewards, Brave Wallet, Brave VPN, Leo, and telemetry.
