performance-rs

Load tests for data serving via axum using different protocol. Given some clients that periodically want to request a list of around 500 strings, what is the best way to server them.

Running via Docker

docker build -t protocol-rs .
docker run -ti -p 3000:3000 protocol-rs

HTTP

Always 5k users making http request every 500ms.

k6 run k6-rest-test.js

SSE

Always 5k users at the same time. The SSE streams gives them data every 500ms. They connect freshly every 5 seconds. This equals 1000 HTTP requests per seconds and 10k data SSE per second.

k6 run k6-sse-test.js

You might want to increase the port range for this:

sudo sysctl -w net.inet.ip.portrange.first=16384

This seems to have less performance than HTTP, only achieves around 80% with 5000 concurrent users.

WebSocket

Always 15k users at the same time. They receive data every 500ms.

k6 run k6-ws-test.js

Test with Gatling

You need Node.js v18 or later (LTS versions only) and npm v8 or later (included with Node.js).

Run the typeScript sample:

cd gatling
npm install
npx gatling run --typescript --simulation ws
