Question

有没有人知道centos7 下 selenium+ chrome慢成翔什么原因？

display = Display(visible=0, size=(800, 600))
display.start()
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--user-data-dir")
chromedriver = "/usr/local/bin/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(executable_path=chromedriver, port=9515, desired_capabilities=chrome_options.to_capabilities(),)
driver.set_page_load_timeout(30)
driver.implicitly_wait(5)
