I tried using Servo with browser.html and found it to be unusably slow, is this ...

Did you use release or debug build? The perf difference in Rust between those is quite staggering

release

Please file a bug with your system specs and specifically what you were trying then. We'll try to get it triaged ASAP.

aand link it here. I tried to build browser.html+servo today on my macos and the browser.html UI feels terribly slow (while servo launched on its own feels fast).

Thanks for the report! Landing a fix for the issue (-b/glutin) right now—I had it queued but never actually got around to landing it.

Thanks, where can I run benchmarks (either the ones in your video or others) so I can compare it against Firefox? It still doesn't "feel" as smooth as Firefox, but then again that could be unrelated to WebRender.

I think it's not really ready for informal benchmarks like that. There are lots of random issues. Feel free to try various pages and file bugs, though.

Don't forget to use the -w switch to enable WebRender.

If that doesn't help, please file a bug. Getting to optimum performance with diverse hardware configurations is a slog, unfortunately, and any and all performance/hardware data is a great help :)

I'm using `gulp servo` which appears to use that switch: https://github.com/browserhtml/browserhtml/blob/master/gulpf... . Used the binary in the target/release folder... not sure what I could have done wrong.
