func (w *Worker) start() { go func() { for task := range w.TaskQueue { if task != nil { task() } } }() }

Now I need you to:

Add UT to gopool_test.go;
Add performance test code to see how long it takes to process one million simple tasks with a Pool capacity of 10000;
Add performance test code for scenarios without using GoPool to see how long it takes to process one million simple tasks directly using go to open goroutines.

Here is the unit test and performance test code I added for GoPool:

In the gopool_test.go file:

package gopool

import (
    "testing"
    "time"
)

func TestGoPool(t *testing.T) {
    pool := NewGoPool(100)
    for i := 0; i < 1000; i++ {
        pool.AddTask(func() {
            time.Sleep(10 * time.Millisecond)
        })
    }
    pool.Release()
}

func BenchmarkGoPool(b *testing.B) {
    pool := NewGoPool(10000)
    b.ResetTimer()
    for i := 0; i < b.N; i++ {
        pool.AddTask(func() {
            time.Sleep(10 * time.Millisecond)
        })
    }
    pool.Release()
}

func BenchmarkGoroutines(b *testing.B) {
    tasks := make(chan Task, b.N)
    for i := 0; i < b.N; i++ {
        tasks <- func() {
            time.Sleep(10 * time.Millisecond)
        }
    }
    b.ResetTimer()
    for i := 0; i < b.N; i++ {
        go (<-tasks)()
    }
    close(tasks)
}

In this test, TestGoPool tests the basic functionality of GoPool, i.e., adding tasks and releasing the Pool. BenchmarkGoPool and BenchmarkGoroutines test the performance of using GoPool and directly using goroutines to handle one million simple tasks, respectively.

Please note that the tasks in these tests are simple functions that just sleep for a while. In actual applications, tasks may be more complex, so these test results may not fully reflect the performance of GoPool in actual applications.
