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:
| System | Limit | Note |
|---|---|---|
| TCP initial congestion window | About 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 headers | 8 KB per header line by default | Data this large must go in the request body. |
| webpack asset modules | 8 KB by default | Assets over the threshold are emitted as files instead of data URIs. |
Use this file for
- Checking thumbnail and icon handling
- Verifying upload filters that allow or block RTF
- Testing legacy document import
Testing notes for RTF
- Two MIME types are in use, application/rtf and text/rtf, and allow-lists should recognise both.
- RTF readers must skip groups they do not understand; a parser that fails on unknown control words is not conformant.
