 This library wants to fill this gap, and it aims to be: 
 - **Cross-platform**: it currently supports Windows, Linux, macOS, and FreeBSD
-- **Performant**: it internally uses low-level system APIs to be more efficient (see [benchmarks](#benchmarks))
+- **Performant**: it focuses on performance (see [benchmarks](#benchmarks)) by internally using low-level system APIs
 - **Simple**: it exposes intuitive APIs to get details about the listening processes
 - **Lightweight**: it has only the strictly necessary dependencies
