Как ускорить разбор с помощью BeautifulSoup?

Question

Я хочу составить список музыкальных c фестивалей в Корее, поэтому я попытался просканировать веб-сайт по продаже билетов на фестивали:

import requests
from bs4 import BeautifulSoup

INTERPARK_BASE_URL = 'http://ticket.interpark.com'

# Festival List Page
req = requests.get('http://ticket.interpark.com/TPGoodsList.asp?Ca=Liv&SubCa=Fes')
html = req.text
soup = BeautifulSoup(html, 'lxml')
for title_raw in soup.find_all('span', class_='fw_bold'):
    title = str(title_raw.find('a').text)
    url_raw = str(title_raw.find('a').get('href'))
    url = INTERPARK_BASE_URL + url_raw

    # Detail Page
    req_detail = requests.get(url)
    html_detail = req_detail.text
    soup_detail = BeautifulSoup(html_detail, 'lxml')
    details_1 = soup_detail.find('table', class_='table_goods_info')
    details_2 = soup_detail.find('ul', class_='info_Lst')
    image = soup_detail.find('div', class_='poster')

    singers = str(details_1.find_all('td')[4].text)
    place = str(details_1.find_all('td')[5].text)
    date_text = str(details_2.find('span').text)
    image_url = str(image.find('img').get('src'))

    print(title)
    print(url)
    print(singers)
    print(place)
    print(date_text)
    print(image_url)

Я использовал для l oop, чтобы просмотреть все страницы с подробностями. на странице списка, но загрузка каждой страницы сведений слишком медленная.

Как ускорить мой код?
