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
- Testing avatar and logo uploads
- Seeding databases and demos
- Testing data import features
Testing notes for CSV
- Splitting each line on commas breaks on quoted fields. Test with the quoted-fields sample before trusting an importer.
- Excel opens CSV files using the system locale, so a file that works in one country shows everything in one column in another.
