Where 50 KB matters

A 51,200-byte file, half of the default body limit in several web frameworks. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Express body parsers	100 KB by default	50 KB is accepted; 500 KB is rejected with 413 unless the limit is raised.
Base64 encoding	Adds 33 percent	50 KB becomes about 67 KB when embedded in JSON.

Testing notes for SQL

Executing an uploaded SQL file is running code. Only do it in an isolated database with a restricted account.
Clients that load the whole script into memory struggle with large dumps; streaming execution matters at 10 MB and above.
