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
  • Verifying text extraction and page counts
  • Exercising virus scanning and content inspection

Testing notes for PDF

  • Page count and file size are unrelated: one scanned page can be larger than a 300-page text document.
  • A file cut off before its final "%%EOF" marker usually cannot be opened, which makes PDF a good format for detecting truncated transfers.
