12 Factor CLI

9 Be speedy
CLIs need to start quickly. Use $ time mycli to benchmark your CLI. Here is a rough guide :

• <100ms: very fast (sadly, not feasible for scripting languages)
• 100ms–500ms: fast enough, aim here
• 500ms-2s: usable, but not going to impress anyone
• 2s+: languid, users will prefer to avoid your CLI at this point
