I always enjoy reading posts about optimization like this one. Optimizing a running service is often underrated. Many engineers focus on scaling horizontally or vertically, adding more instances or using more powerful machines to solve problems. But there’s a third option: service optimization, which offers significant benefits. Whether it's tuning TCP configurations or profiling to identify CPU and memory bottlenecks, optimizing the service itself can lead to better performance and cost savings. It’s a smart approach that shouldn’t be overlooked.
