Thats the feeling I get when reading blog post on Rust compiler 
speed improvements.

The other thing to keep in mind is that you need to be mindful 
about what CPU resources are limiting your performance because if 
you change your algorithm to use more D-cache and it shows speed 
improvements in micro benchmarks if your application is already 
starving for D-cache you would reduce performance when you add 
that change to whole application.
