Wasabi Benchmark Suite

[!WARNING] These benchmark tests can only be run within the Microsoft Excel environment.

This folder contains a self-contained benchmark harness for Wasabi’s core primitives. It measures raw CPU throughput, independent of network latency, using the same native Windows APIs that Wasabi calls internally.

What is tested

Operation	Description
SHA‑1	Cryptographic hash used during the WebSocket handshake (CryptoAPI)
Base64Encode	Encoder used for handshake keys and proxy auth (`CryptBinaryToStringW`)
StringToUtf8	Conversion from VBA String to UTF‑8 bytes (`WideCharToMultiByte`)
Utf8ToString	Conversion from UTF‑8 bytes to VBA String (`MultiByteToWideChar`)
BuildWSFrame	Full WebSocket frame construction, including `CryptGenRandom` mask

Prerequisites

Wasabi.bas must be in the same VBA project.
The 7 public wrapper functions listed at the bottom of WasabiBenchmark.bas must be added to Wasabi.bas.

How to run

Import WasabiBenchmark.bas into your VBA project.
Run WasabiBenchmark_RunAll from the Immediate Window or Macro dialog.

Interpreting the results

Avg Latency (µs) – average microseconds per operation.
Throughput (MB/s) – how many megabytes per second the operation processes.
Ops/s (k) – thousands of operations per second.

The suite uses QueryPerformanceCounter for sub‑millisecond accuracy and automatically adapts iteration counts to the payload size.

Reference chart

Throughput Benchmark

The chart plots throughput against payload size on a logarithmic scale, highlighting the performance difference between operations.
