A collection of docker files used to benchmark tile generation software and scripts. Most of these images are just the official images for the respective tile generation softwares with hyperfine added. Was used in the bachelor's thesis The Server-side of Tiled Raster Web Maps: benchmarking and evaluating static raster tile map generation tools for geospatial data processing and visualization. I will refer to that for further details.
All benchmarks and measurements was done in the spring of 2023 and the newest versions of the respective programs at that time.
