Where 10 KB matters

A 10,240-byte file that still arrives in the first round trip of a new connection. These are the default limits a file of this size is useful for testing:

SystemLimitNote
TCP initial congestion windowAbout 14.6 KB (10 segments)A 10 KB response fits in the first flight of packets; the 25 KB sample does not.
nginx and Apache request headers8 KB per header line by defaultData this large must go in the request body.
webpack asset modules8 KB by defaultAssets over the threshold are emitted as files instead of data URIs.

All 10 KB sample files

Use this file for

  • Checking thumbnail and icon handling
  • Load-testing map rendering with many features
  • Testing map layers and spatial queries

Testing notes for GeoJSON

  • Swapped latitude and longitude put points in the wrong hemisphere or the ocean. Test with locations you can recognise.
  • Polygon rings must be closed, with the first and last positions identical.
