 ## Benchmarks
 
 The benchmark is a simple `hello world` [example](benchmarks/benchmark.js) using a
-number of unix sockets (connections) with a pipelining depth of 10 running on Node 16.
-The benchmarks below have the [simd](https://github.com/WebAssembly/simd) feature enabled.
+number of unix sockets (connections) with a pipelining depth of 10 running on Node 20.6.0.
