 Bevy works great using Rust's default configuration. However, if you know your way around a compiler and find that Bevy's iterative compilation times are still too slow for you, try fine-tuning the following options:
 
-* **Enable Bevy's Dynamic Linking Feature**: This is the most impactful compilation time decrease! If `bevy` is a dependency, you can compile the binary with the "dynamic_linking" feature flag (enables dynamic linking). **Important!** On Windows you _must_ also enable the [perfomance optimizations](#compile-with-performance-optimizations) or you will get a [`too many exported symbols`](https://github.com/bevyengine/bevy/issues/1110#issuecomment-1312926923) error.
