如何优化Go语言开发中的网络连接池管理

type ConnectionPool struct {
    pool chan net.Conn
}

func NewConnectionPool(size int, factory func() (net.Conn, error)) (*ConnectionPool, error) {
    pool := make(chan net.Conn, size)

    for i := 0; i < size; i++ {
        conn, err := factory()
        if err != nil {
            return nil, errors.New("failed to create connection")
        }

        pool <- conn
    }

    return &ConnectionPool{pool: pool}, nil
}

func (p *ConnectionPool) GetConn() net.Conn {
    return <-p.pool
}

func (p *ConnectionPool) ReleaseConn(conn net.Conn) {
    p.pool <- conn
}

func main() {
    pool, err := NewConnectionPool(10, func() (net.Conn, error) {
        return net.Dial("tcp", "localhost:8080")
    })

    if err != nil {
        fmt.Println("failed to create connection pool")
        return
    }

    conn := pool.GetConn()
    // do something with the connection

    pool.ReleaseConn(conn)
}

func (p *ConnectionPool) GetConn() (net.Conn, error) {
    select {
    case conn := <-p.pool:
        return conn, nil
    case <-time.After(timeout):
        return nil, errors.New("connection pool timeout")
    }
}

func (p *ConnectionPool) CheckConn() {
    for conn := range p.pool {
        // do health check on conn
        // if conn is not healthy, close and discard it
        // create a new connection and put it into pool
    }
}

func (p *ConnectionPool) AdjustPoolSize() {
    // check current workload
    // increase or decrease pool size accordingly
}
