It’s impressive to hear about your extensive experience with Go and your dedication to performance optimization. Go’s design philosophy makes it a fantastic choice for many projects, but as you’ve noted, there are scenarios where other languages might outshine it. When it comes to scalability on systems with a large number of CPU cores, Go’s concurrency model may hit some limitations. However, with your expertise and focus on efficiency, you’re already ahead of the game. Keep exploring optimization techniques, and don’t hesitate to dive into other languages if they better suit your needs. Your dedication to squeezing the most out of Go is inspiring!
