Google has released version 1.1 of its Go programming language. "The most significant improvements are performance-related," blogged Google's Andrew Gerrand. "It is likely that your Go code will run noticeably faster when built with Go 1.1."
Most of that speed comes from optimizations to the compiler and linker, garbage collector, scheduler and parts of the standard library. In addition, a new race detector means the language works better in systems running multi-core processors, and new return requirements will force Go developers to write more succinct code.
