cargo-pgo Cargo subcommand that makes it easier to use PGO and BOLT to optimize Rust binaries.

Comparing Rust's and C++'s Concurrency Library

1. By default, the Rust compiler rustc does no speed/size optimizations (-C opt-level=0).

2. rustc supports three levels of optimization for speed (-C opt-level=1, -C opt-level=2 and -C opt-level=3) and 2 levels of optimization for size (-C opt-level=s and -C opt-level=z).

3. rustc -O is equivalent to rustc -C opt-level=2 and cargo build --release uses the release profile which defaults to -C opt-level=3.

4. pass a 24-byte object by value vs by reference. not big differeence, but generally prefer passing by reference as it gives the compiler more flexibility for optimizations.
