Mozilla’s Servo engine written in Rust outperforms other engines by far
While the Rust-written Servo engine being developed by Mozilla is still experimental, Google's Jake Archibald has done a performance comparison of Servo against other engines and the results are mighty impressive.
While Archibald did these tests on OS X, the results are interesting enough to share. The test includes an animated background, transform, and border radius on 499 elements:
Chrome Canary - 15 FPS
Mozilla Firefox Developer - 9 FPS
Apple WebKit Nightly - 5 FPS
Mozilla Servo - 60 FPS
Servo is delivering some serious performance. The test appears to be done with Servo's new GPU-accelerated rendering backend.
Servo is experimental and is not part of the current stable Firefox releases.
