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
  • Testing feed readers and SOAP clients
  • Testing XML parsers and data import

Testing notes for XML

  • Namespaces change element identity: <name> in two namespaces is two different elements.
  • Parsers that resolve external entities can be made to read local files or call internal services, an attack called XXE. Disable DTD processing for untrusted input.
