Hi OSGeo community,
I’ve been actively developing Qtiler, an open-source lightweight WebGIS tile server, and recently ran some performance tests to evaluate its caching and rendering speeds under load.
To establish a solid baseline, I recorded a direct side-by-side benchmark comparing Qtiler’s architecture against GeoWebCache. The test demonstrates some very interesting metrics regarding response times and resource efficiency when serving tiles.
For those interested in server performance and WebGIS optimization, I’ve uploaded a short video capturing the raw results here:

I would really appreciate any feedback from this community regarding the architecture, the results, or the testing methodology itself. The source code is fully available on GitHub for anyone who wants to dive in or reproduce the setup.
Best regards,
Abel Gonzalez
