Make Slow Code Faster ChatGPT Prompt

धीमे कोड को तेज़ बनाएं

I need a performance expert. My code is too slow when the input grows.

[paste your slow code here]
Language and version: [e.g. Python 3.12, Node 22, Java 21]
Typical input size: [e.g. 10,000 rows, a 2 GB file, 500 API calls]
Where it runs: [laptop, server, phone, browser]

Work through it like a profiler would:
1. **Bottleneck hunt** – point to the exact lines that cost the most time or memory, and explain why.
2. **Complexity** – current time and space complexity in Big-O, with a one-line reason.
3. **Optimised version** – rewritten code, with comments only where the change is not obvious.
4. **New complexity** – and a rough estimate of the speed-up for my input size.
5. **Measure it** – a small benchmark snippet I can run to compare old and new.
6. **Trade-offs** – anything that got harder to read or uses more memory.

Prefer simple wins first (better data structures, fewer loops, caching, batching) before clever tricks. Keep the output identical, and tell me if the real fix is outside the code, such as a database index or a slower network.

How to use it

1. Copy the prompt.
2. Open ChatGPT or Gemini and paste it.
3. Replace anything in [square brackets] with your own details, then send.
4. Ask for changes: "shorter", "more formal", "in Hindi".
