I'm trying to make a queue struct that have push and pop functions.

I need to use 10 threads push and another 10 threads pop data, just like i did in the code below.

Questions : 1. I need to print out how much i have pushed/popped, but i don't know how to do that. 2. Is there anyway to speed up my code ? the code is too slow for me.

package main

import (
    "runtime"
    "time"
)

const (
    DATA_SIZE_PER_THREAD = 10000000
)

type Queue struct {
    records string
}


func (self Queue) push(record chan interface{}) {
    // need push counter
    record <- time.Now()
}

func (self Queue) pop(record chan interface{}) {
    // need pop counter
    <- record
}

func main() {
    runtime.GOMAXPROCS(runtime.NumCPU())
    //record chan
    record := make(chan interface{},1000000)
    //finish flag chan
    finish := make(chan bool)
    queue := new(Queue)
    for i:=0; i<10; i++ {
        go func() {
            for j:=0; j<DATA_SIZE_PER_THREAD; j++ {
                queue.push(record)
            }
            finish<-true
        }()
    }
    for i:=0; i<10; i++ {
        go func() {
            for j:=0; j<DATA_SIZE_PER_THREAD; j++ {
                queue.pop(record)
            }
            finish<-true
        }()
    }
    for i:=0; i<20; i++ {
        <-finish
    }
}
