[NOTES] Web-frameworks: Stress-testing with wrk2

Stress-testing your API with wrk2

I recently re-wrote a micro-service in Rust to boost performance. I have used locust and Jmeter for stress testing before but I always found them slow to configure. Today I found wrk2 and it's pretty neat and lightweight. These are my notes:


Assuming you are working on Ubuntu:

sudo apt-get update
sudo apt-get install -y build-essential libssl-dev git zlib1g-dev
sudo git clone https://github.com/giltene/wrk2.git
cd wrk2
sudo make
# move the executable to somewhere in your PATH
sudo cp wrk /usr/local/bin

Setting up a post-request:

Create a lua file: test-config.lua

wrk.method = "POST"
wrk.body = "{\"foo\": \"bar\"}"
wrk.headers["Content-Type"] = "application/json"

Test it like this:

wrk2 -t500 -c1000 -d160s -R10000 -s ~/Documents/luaTestScript.lua http://localhost:8080/test_endpoint


  • t500: 500 concurrent threads
  • c1000: 1000 connections
  • d160s: duration of 160 seconds
  • R10000: request-throughput of 10000
  • s: script

Their github repo here: https://github.com/giltene/wrk2

Closing note: The improvement that this provides over wrk is that it can allow you to specify the throughput at which we want to stress-test
