All_examples2 runs faster in the browser?

Any reason why the examples run so much slower when I run them locally compared to the demos running in the browser with WASM and WebGL?

PS C:\projects\nphysics> rustc --version
rustc 1.48.0 (7eac88abb 2020-11-16)

PS C:\projects\nphysics> cargo version
cargo 1.48.0 (65cbdd2dc 2020-10-14)

cargo run --release --bin all_examples

Video Demo


Maybe I am not reading the video right, but looking at the physics computation times on the top-left of the window, it appears that the native version is slightly faster than the WASM version. Or did I miss something?

How about this video?
