Speed up slow code with AI, using measurements
Guessing at performance wastes time.
What to do
- Measure with a profiler before optimizing.
- Give the bot the hot function and the profiler numbers.
- Ask about algorithmic complexity first, micro-optimizations last.
- Re-measure; keep tests passing.
Copy this prompt
This function takes [x ms] and is [y%] of runtime per the profiler. Input sizes: [n]. Suggest optimizations ranked by expected impact, with Big-O before/after.
[paste]Check the bot's work
Benchmark before and after.
Questions
Can I trust the bot on performance?
Use it to plan and explain, then verify. Benchmark before and after.
