I Crashed My Server with Promise.all() - Here's How I Built a 121 RPS Fuzzer Instead

Developer shares the journey of optimizing 404fuzz, a directory fuzzer, from a naive Promise.all() approach that crashed systems to achieving 121 RPS. The evolution involved implementing bounded concurrency queues, leveraging Node.js cluster module for multi-core processing, and discovering that fewer workers with higher concurrency outperforms more workers due to inter-process communication overhead.
