Benchmark for MVT vector tile creation and delivery from a PostGIS database.

The benchmark uses a minimal subset of the NaturalEarth 4.1 data set.

Measurement targets:

• How long does it take to generate all tiles (single node / multiple nodes)
• How many requests/s does the tile server deliver in web server mode

• Tileset name: ne_countries
• Maxzoom level for tile data: 6
• SRS (data and tiles: EPSG:3857 (Web Mercator)

Layer definition:

A reference Mapbox GL JS style for the produced tiles is natural-earth-countries.json.

Requirements:

• Make
• Docker & docker-compose
• gnuplot

Quick benchmark:

make quick_bench

Full benchmark:

• Copy the skeletion directory to a new directory named after your software
• Add a configuration for your software to create a tileset following the definition above
• Adapt the Makefile or add a script to run the benchmarks with your software, using docker containters, if possible
• Add calls to the project Makefile from the top level Makefile
• Open a pull request on Github

The database can be started within a Docker container with

docker-compose up -d mvtbenchdb

PostgreSQL is running on Port 5432 within Docker and is mapped to 127.0.0.1:5439 on the Docker host.

• DB user: mvtbench
• DB password: mvtbench

Connection example:

PGPASSWORD=mvtbench psql -h 127.0.0.1 -p 5439 -U mvtbench

# Set Postgresql environment variables when needed: PGHOST, PGPORT, PGUSER, PGPASSWORD
cd data
make createdb
