Go Escape Analysis Flaws Dmitry Vyukov, @dvyukov Feb 10, 2015 Abstract The default Go compiler (gc) does escape analysis to identify objects that can be allocated on stack. This optimization is very useful because stack allocations are significantly cheaper for both memory allocator and garbage c...

I originally proposed this as a GopherCon talk on writing “high-performance Goâ€, which is why it may seem rambling, incoherent, and—at times—not at all related to Go. The talk was rejected (probably because of the rambling and incoherence), but I still think it’s a subject worth exploring. The good news is, since it was rejected, I can take this where I want. The remainder of this piece is mostly

We discuss the Go Circuit project and set it in the context of an inevitable and oncoming shift in the development and runtime stacks of the Internet age. We argue that the programming language is the right place to abstract access to a hardware clusters as a "Single-System Image". On the way, we appeal to the success of Erlang in the Telecom industry and discuss why it has not yet inspired Intern

GitHub - julienschmidt/httprouter: A high performance HTTP request router that scales well
HttpRouter is a lightweight high performance HTTP request router (also called multiplexer or just mux for short) for Go. In contrast to the default mux of Go's net/http package, this router supports variables in the routing pattern and matches against the request method. It also scales better. The router is optimized for high performance and a small memory footprint. It scales well even with very
