Description

Hello

I want to convert a 100mb geojson file stored on disk with tippecanoe, I pass the -P param and set the TIPPECANOE_MAX_THREADS env to 8 but it takes around 20-30 seconds to generate the output. How can I improve the performance of this process?

Research direction

Start by reproducing the tippecanoe conversion with the 100 MB on-disk GeoJSON file, -P, and TIPPECANOE_MAX_THREADS=8. Measure where the 20–30 seconds is spent, then document whether the process has an actionable bottleneck or configuration change that improves the output time.
