Is Go Fast? Go is faster than interpreted languages like python in terms of sheer execution since it’s compiled to native executable format. Go is slower than other compiled languages like C,Rust in terms of execution. This is primarily because although compiled go runs with a ‘runtime’ which does some housekeeping (scheduling and multiplexing goroutines, managing/freeing memory (GC) etc). This overhead is much smaller than a virtual machine required for languages like java but is an overhead nonetheless.
