Speed up a slow API endpoint or function
This prompt works like a performance review: it finds the biggest slowdowns first, estimates what each one costs, and shows the fix. Paste the code, the queries it runs and real timing numbers if you have them.
Act as a performance engineer. This [ENDPOINT OR FUNCTION, e.g. GET /orders] takes [TIME, e.g. 4 seconds] and should take under [TARGET, e.g. 300 ms]. Code: [PASTE] Database queries or ORM calls it makes: [PASTE OR DESCRIBE] Data size: [e.g. 200k orders, 5k users] Find the biggest slowdowns first (N+1 queries, missing indexes, loops inside loops, repeated work, large payloads). For each, estimate how much time it costs, show the fix, and tell me how to measure before and after. Change only what gives a real gain.
Paste real timing numbers or a profiler output if you have them. Guesses about performance are often wrong.
