+This directory contains code uses to measure the performance of the Vanadium RPC stack.
+
+---
+
+This benchmarks use Go's testing package to run benchmarks. Each benchmark involves
+one server and one client. The server has two very simple methods that echo the data
+received from the client back to the client.
+
+* `client ---- Echo(payload) ----> server`
+* `client <--- return payload ---- server`
+
+There are two versions of the Echo method:
+
+* `Echo(payload []byte) ([]byte], error)`
+* `EchoStream() <[]byte,[]byte> error`
+
+# Microbenchmarks
+## `benchmark_test.go`
+
+The first benchmarks use the non-streaming version of Echo with a varying
+payload size. The second benchmarks use the streaming version with varying
+number of chunks and payload sizes. The third one is for measuring the
+performance with multiple clients hosted in the same process.
+
+This test creates a VC before the benchmark begins. So, the VC creation
+overhead is excluded.
