在python中分散绘制一对2D列表的最有效方法是什么？

import multiprocessing
import threading

def draw(data):
    # 绘制逻辑
    pass

def draw_with_threads(data_list):
    threads = []
    for data in data_list:
        thread = threading.Thread(target=draw, args=(data,))
        thread.start()
        threads.append(thread)
    
    for thread in threads:
        thread.join()

def draw_with_processes(data_list):
    processes = []
    for data in data_list:
        process = multiprocessing.Process(target=draw, args=(data,))
        process.start()
        processes.append(process)
    
    for process in processes:
        process.join()

data_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]  # 2D列表示例
draw_with_threads(data_list)  # 使用多线程进行绘制
draw_with_processes(data_list)  # 使用多进程进行绘制
