Will Rust allow speeds 10x times that of C?

or are rust evangelists delusional?

Depends on what task we're talking about. Probably not.

No one has ever said that.

check their reddit

lets say Firefox itself

given its designed for superscalar tier architectures? probably not. if you're willing to autism it out on some special snowflake DSP, maybe, but you'd likely be abusing intrinsics and stub asm in C for that target as well.

Futhark has the potential I suppose to be 10x faster than C since it was explicitly designed for parallelism and targets where parallelism isn't some magical superscalar abstraction.

Firefox is currently written in C++. It all depends on how bad some piece is currently implemented and how well the Servo team can implement it in Rust.

I don't know what in the Rust language would clearly give such a speed up. The benefits of Rust are mostly safety.

Even if you think that the C++ implementation is super bad at parallelism and the Rust one would be great at that, you still get Amdahl's law holding you back.

"10 times faster than C" isn't happening unless you're gonna do threading (or if the C program is poorly written). That said the language is extremely fast while providing high level abstraction, it's pretty comfy once you get used to it. It won't be *replacing* C though, unfortunately. Or maybe it will, I just hope something will soon.

Rust allows estrogen levels 10x that of C

ctard mad cause there are fast as fuck languages that arent 500 years old and a pain in the ass to write in
