Spwn

An HTTP benchmarking program inspired by wrk and Siege.

My motivation

I primarily developed this tool to play with Rust and Tokio.

Features

• User-configurable number of concurrent connections
• User-configurable number of threads to use
• User-configurable duration to run the benchmark
• Request count (total and per second)
• Latency distribution

Example

The following example will fire requests, maintaining 100 connections, to localhost:8080 for 2 seconds using 4 threads.

spwn http://localhost:8080 -d2 -c100 -t4

Building

Rust Nightly 1.17 (2017-02-03) is tested.

The following will build an optimized binary.

cargo build --release
