Frequently Asked Questions

Will text editors handle a 1MB file?

All modern editors (VS Code, Sublime Text, Vim, Notepad++) handle 1MB files instantly. This file is useful for testing that your own text display component handles large content without lag or truncation.

How long does reading 50,000 lines take?

In-memory read: ~5ms on modern hardware. Line-by-line streaming: ~20–50ms. If your implementation takes longer, check for unnecessary string copying or synchronous I/O blocking.
