 TinyWasm is not designed for performance, but rather for size and portability. However, it is still reasonably fast.
-There are a couple of low-hanging fruits on the performance side, but they are not a priority at the moment.

 With all these features disabled, TinyWasm only depends on `core`, `alloc` and `libm` and can be used in `no_std` environments.
-Since `libm` is not as performant as the compiler's built-in math intrinsics, it is recommended to use the `std` feature if possible (at least [for now](https://github.com/rust-lang/rfcs/issues/2505)).
