ZEEF. Profiling and optimizing Go web applications - Artem Krylysov. Go has a powerful built-in profiler that supports CPU, memory, goroutine and block (contention) profiling. Enabling the profiler Go provides a low-level profiling API runtime/pprof, but if you are developing a long-running service, it's more convenient to work with a high-level net/http/pprof package. All you need to enable the profiler is to import net/http/pprof and it will automatically register the required HTTP handlers: If your web application is using a custom URL router, you'll need to register a few pprof HTTP endpoints manually: That's it, launch the application, and then use the pprof tool: go tool pprof [binary] One of the biggest pprof advantages is that it has low overhead and can be used in a production environment on a live traffic without any noticeable performance penalties.
But before digging deeper into pprof, we need a real example which can show how to identify and fix performance issues in Go. Example: Left-pad microservice Note. Untitled.

Why should you learn Go? – Keval Patel – Medium. Go has goroutines !! As we discussed above, hardware manufacturers are adding more and more cores to the processors to increase the performance. All the data centers are running on those processors and we should expect increase in the number of cores in upcoming years. More to that, today’s applications using multiple micro-services for maintaining database connections, message queues and maintain caches. So, the software we develop and the programming languages should support concurrency easily and they should be scalable with increased number of cores.
But, most of the modern programming languages(like Java, Python etc.) are from the ’90s single threaded environment. For an example, creating new thread in Java is not memory efficient. On the other hand, Go was released in 2009 when multi-core processors were already available. Other benefits are : Goroutines have growable segmented stacks. Golang Üzerine – Oğuzhan Blog. İlk defa Postfix’in kuyruklama istatistiklerini self-hosted çalışan ve raporlayan bir sistem tasarlarken Go’yu keşfetmiştim. İçindeki net/http paketi’, template yapısı ve hızı direk karar vermemi sağladı. Bir öğleden sonrada oturup syntax’i çözüp direk bodozlama kodlamaya başladım. Sonra lazım olan her yerde basit yazılan bu dili, script dili niyetine kullanırken buldum kendimi. En son Netdirekt‘den Semih‘in gazlaması “Production’da da Go kullansak mı?”
Diye ciddi ciddi düşünür oldum ve şimdi MaestroPanel’in bir çok yerinde kullanıyoruz.Ha! Bu arada bir projeyi yine Go ile kotarıp ilk paramı kazanınca böyle bir yazı yazmayı kendime bir borç bildim. Go’ya direkt balıklama dalmak istersen adresinden devam edebilirsin. Kim? Go 28 Mart 2012’de version 1’e ulaşmış fakat ilk piyasada görülmesi 2009’a dayanıyor. Go takımı ile tanışmak isterseniz bu videoyu izleyebilirsiniz Go’da ilk fark edeceğiniz şey basitlik. Şekil Go Logosu Un-Googleable Object-Orient? Var x int. MM - React Native, Golang, .NET.
