Golang 1.7

Golang 1.7 主打更小的 binary size:「Smaller Go 1.7 binaries」:

Typical programs, ranging from tiny toys to large production programs, are about 30% smaller when built with Go 1.7.

還附了一張經典的「Hello, world」程式的分析:

由於現代 CPU 的速度與 L1/L2/... cache 有緊密關係,當 binary size 變小時,常常會伴隨著 memory access 變快 (因為 hitrate 提昇),所以 binary size 也是效能指數蠻重要的一環。
