Load Testing Caddy Web Server on a GCP F1-Micro Instance Using K6 (k6.io)

March 24, 2020

TL;DR: I used the K6 load testing framework to benchmark the Compute Engine f1-micro and Caddy web server hosting this site. With CloudFlare caching turned off, the server was able to serve an onslaught 800 virtual users continuously reloading the page (while maintaining a median request duration of <400ms), but started dropping requests when increasing the load further.

This is fine.
