How is Go’s compilation performance on darwin/arm64? I did a rough and non-rigorous comparison of Go compilation performance between an Intel Mac and an M1 Mac. This compilation report was generated with the following commands:
$ go build -gcflags='-bench=bench.out' -a
$ cat bench.out
where -a disables the compilation cache.

Go在darwin/arm64上的编译性能怎么样？我很不严谨的粗略比较了Intel Mac 和 M1 Mac 的 Go 编译性能。这个编译报告由如下指令生成:
$ go build -gcflags='-bench=bench.out' -a
$ cat bench.out
其中-a用于禁用编译缓存。
