Golang简单的对象池复用的好处 减少gc压力减少内存不必要的内存分配import ( "fmt" "sync")var bufPool sync.Pooltype buf struct { b []byte}func main() { for { var bf *buf // 从池中取数据 v := buf

Golang获取goroutine IDpackage mainimport ( "bytes" "fmt" "runtime" "strconv")func main() { fmt.Println(getGID())}func getGID() uint64 { b := make([]byte, 64) b = b[:runtime
