 # Performances benchmark
 Discover the staggering performance of OpenSTL in comparison to [numpy-stl](https://github.com/wolph/numpy-stl),
  [meshio](https://github.com/nschloe/meshio) and [stl-reader](https://github.com/pyvista/stl-reader), thanks to its powerful C++ backend.
