+# Libcrux Benchmarks
+
+This crate is used to benchmark libcrux and compare it to 3rd party implementations.
+
+## lib25519
+Comparing with lib25519 only works on Linux.
+To enable it first build the sys crate 
+
+```bash
+cd ../sys/lib25519
+./build-native.sh
+
+RUSTFLAGS="--cfg crypto_lib25519" cargo criterion --bench x25519
+```
