Quest: Terminal Enchantment — Challenge 2 Purpose: Reference benchmark data for common Oh-My-Zsh themes

---

Sample Results (Apple Silicon Mac)

Theme	Avg Prompt Time (ms)	Status
robbyrussell	~5.00	✅
agnoster	~4.80	✅
clean	~5.20	✅

Interpretation Guide

Time Range	Rating	Notes
< 10ms	🟢 Excellent	Imperceptible delay
10–50ms	🟡 Good	No noticeable lag
50–200ms	🟠 Acceptable	Slight delay on each prompt
> 200ms	🔴 Slow	Investigate plugin/theme load times

Notes

• Times will vary significantly based on hardware, shell plugins, and system load
• The benchmark script measures ZSH_THEME variable assignment, not full prompt rendering
• For a more accurate test in production, use: time zsh -ic exit
• All three default themes tested should fall well under 50ms
• agnoster is the recommended choice for this quest (balance of features and speed)
