Solved: Why do I still feel broke even though the business is doing well?

🚀 Executive Summary TL;DR: The ‘Broke Billionaire’ server problem describes powerful hardware performing poorly due to overlooked system bottlenecks, like hard-coded connection limits or exhausted file descriptors. Solving this requires deep investigation to identify the slowest component, followed by targeted fixes ranging from temporary resource limit adjustments to full architectural re-designs. 🎯 Key Takeaways A system’s performance is dictated by its slowest component; simply adding more hardware without understanding the bottleneck is an expensive and ineffective solution. Performance bottlenecks are often subtle, manifesting as low overall resource utilization but with specific constraints like a single CPU core pinned or exhausted file descriptors, requiring detailed profiling and detective work. Solutions to performance bottlenecks range from immediate, temporary resource limit adjustments (e.g., prlimit for file descriptors) to permanent configuration changes (e.g., systemd L
