NotCookey/PsyFlood ? reverse-engineered prompt

Build me a simple Python tool for testing the performance of my own website under load.

I want it to send lots of normal HTTP requests at the same time, let me set the target URL, number of workers, request count, and how fast it sends traffic, then show me clear results like success rate, errors, and total time. Make it easy to run from one script, and add basic safety checks so it is only meant for sites I own or have permission to test. If you need to look up current docs online, feel free to do that.
