+## Benchmark - Tiny Keccak
+
+Rust based `tiny_keccak` benchmark test case.
+
+Build with
+
+```
+cargo build \
+    --package wasmi_benches_tiny_keccak \
+    --profile wasm \
+    --target wasm32-unknown-unknown
+```
+
+Post-optimize with `wasm-opt` using:
+
+```
+wasm-opt \
+    -O3 \

+    -o target/wasm32-unknown-unknown/wasm/wasmi_benches_tiny_keccak.opt.wasm
+```
+
+Finally move the post-optimized Wasm binary into the proper place:
+
+```
+cp \
+    target/wasm32-unknown-unknown/wasm/wasmi_benches_tiny_keccak.opt.wasm \
+    crates/wasmi/benches/rust/tiny_keccak.wasm
