Where 25 KB matters
A 25,600-byte file: the size of a small web image or a short document. 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) | 25 KB needs at least two flights of packets on a new connection. |
| Base64 encoding | Adds 33 percent | A 25 KB file becomes about 34 KB inside JSON or an email. |
Use this file for
- Checking thumbnail and icon handling
- Loading test data into a database in bulk
- Testing data pipelines that split fields on tabs
Testing notes for TSV
- Windows does not open .tsv in Excel by default, so users rename files to .txt or .csv, and the extension stops describing the content.
- A field cannot contain a tab or a line break. Exporters deal with that in incompatible ways: some write backslash escapes such as \t, some apply CSV-style quotation marks, and some corrupt the row.
