pprof的inuse_space和linux top查看的RES差别很大

送你一段代码，RES是这么算的 RES=HeapInuse + HeapIdle - HeapReleased

package main

import (
    "fmt"
    "runtime"
    "time"
)

func main() {
    fmt.Printf("%v\t%v\t%v\t%v\n", "HeapInuse", "HeapIdle", "HeapReleased", "RES")
    for i := 0; i < 200; i++ {
        _ = make([]int, i*1000000)
        m := runtime.MemStats{}
        runtime.ReadMemStats(&m)
        fmt.Printf("%v\t%v\t%v\t%v\n", m.HeapInuse, m.HeapIdle, m.HeapReleased,   m.HeapInuse + m.HeapIdle - m.HeapReleased)
        time.Sleep(time.Second)
    }
}
