无法使脚本（使用多重处理创建的）运行更快

Question

我已经在python中创建了一个脚本，以从imdb.com提取与不同演员的名字相关的所有链接，然后解析他们电影的前三个链接，最后抓取这些电影的导演和作家的名字。 大约有1000个名字。 在此示例中，我使用了前十个名称。 然而，问题是，即使我用multiprocessing ，如concurrent.futures脚本中，我发现这不是加快。

网站连结

回顾一下-脚本首先使用上面的链接，然后从此处解析前三个电影链接：

然后从此处解析导演和作家的姓名：

这是我尝试过的：

import requests
import concurrent.futures
from bs4 import BeautifulSoup
from urllib.parse import urljoin

url = 'https://www.imdb.com/list/ls058011111/'
base = 'https://www.imdb.com/'

def get_actor_list():
    res = requests.get(url,headers={"User-Agent":"Mozilla/5.0"})
    soup = BeautifulSoup(res.text,"lxml")
    for name_links in soup.select(".mode-detail")[:10]:
        name = name_links.select_one("h3 > a").get_text(strip=True)
        item_link = urljoin(base,name_links.select_one("h3 > a").get("href"))
        yield name,item_link

def get_movie_links(name,link):
    itemvault = []
    r = requests.get(link)
    soup = BeautifulSoup(r.text,"lxml")
    item_links = [urljoin(base,item.get("href")) for item in soup.select(".filmo-category-section .filmo-row > b > a[href]")[:3]]

    with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
        future_to_url = {executor.submit(get_content,url): url for url in item_links}
        for future in concurrent.futures.as_completed(future_to_url):
            itemvault.append(future.result())

    print(name,itemvault)


def get_content(url):
    res = requests.get(url,headers={"User-Agent":"Mozilla/5.0"})
    soup = BeautifulSoup(res.text,"lxml")
    try:
        director = soup.select_one("h4:contains('Director') ~ a").get_text(strip=True)
    except Exception as e: director = ""
    try:
        writer = soup.select_one("h4:contains('Writer') ~ a").get_text(strip=True)
    except Exception as e: writer = ""
    return director,writer

if __name__ == '__main__':
    for elem in get_actor_list():
        get_movie_links(elem[0],elem[1])

脚本产生的结果类型（按预期）：

Robert De Niro [('', 'Anthony Thorne'), ('Jonathan Jakubowicz', 'Jonathan Jakubowicz'), ('Martin Scorsese', 'David Grann')]
Jack Nicholson [('Rob Reiner', 'Justin Zackham'), ('Casey Affleck', 'Casey Affleck'), ('James L. Brooks', 'James L. Brooks')]
Marlon Brando [('Peter Mitchell Rubin', 'Mario Puzo'), ('Bob Bendetson', 'Bob Bendetson'), ('Paul Hunter', 'Paul Hunter')]

如何使上述脚本运行得更快？
