How does this relate to the async animations we are already performing on the compositor thread today? Isn't that sufficient for most animations people want? (transform, opacity). Andreas On Oct 13, 2013, at 1:43 PM, Patrick Walton wrote: > This did make me realize something, however: If the

Proof-carrying code and type preserving compilation allow securing even fairly complex compiler optimizations to be done securely. Sprinkle process separation/isolation and lowered rights onto that and I don’t think fast JS has to be a significant security risk. Thanks, Andreas > On Nov 11,

Does anyone have profiling numbers that Azure on top of Skia has a measurable performance overhead? Thanks, Andreas > On Nov 11, 2014, at 2:53 PM, Cameron Zwarich wrote: > > On Nov 11, 2014, at 1:19 PM, Patrick Walton wrote: >> >> On 11/11/14 1:02 PM, Robert O'Callahan wrote: >>> https://gi

We should experiment with parallel software rendering. Using skia on many cores might be faster than using D2D in practice, for example. Andreas > On Nov 12, 2014, at 12:02 PM, Jack Moffitt wrote: > >> Incidentally, I see no reason to move away from Azure, given how nice >> Direct2D is on Windo

There are easier ways to compare. D2D is something like 40% faster than software (Bas, is that the right ballpark?). So if you get a 2x+ speedup with concurrent software rendering, you win. Thanks, Andreas > On Nov 12, 2014, at 12:08 PM, Jack Moffitt wrote: > >>> We should experiment with p
