+## 📊 Benchmarks
+
+The benchmark is available in the [XenoAtom.Allocators.Bench](src/XenoAtom.Allocators.Bench/Program.cs).
+
+It is comparing the performance of the TLSF allocator against the standard `malloc`/`free` from the C runtime library.
+
+The benchmark consists of making 2048 allocations and frees within a range of random sizes between `64, 96, 150, 200, 400, 1024, 4096` bytes.

+The benchmark shows that the **TLSF allocator is 20%+ faster** than the standard `malloc`/`free` from the C runtime library.
