What are the most useful curl opts for debugging and performance? or How do you optimize your request

`-L` is a must, but `--resolve` is my secret weapon. Bypass DNS and go straight to the IP. Perfect for testing before DNS updates.

Also, `-m 5` instead of `--max-time` because I’m lazy and it does the same thing.

For JSON, `-d @file.json` saves me from escaping hell. Just dump your payload in a file and go.

Oh, and `-I` for HEAD requests. Faster than a full GET when you just need headers.
