您可以使用下面的代码来提取性能指标

from selenium.webdriver.common.by import By
    from selenium import webdriver
    
    driver = webdriver.Chrome()
    
    # Navigate to the page you want to test
    driver.get('https://url.com')
    driver.implicitly_wait(40)
    
    # Start profiling
    driver.execute_cdp_cmd('Performance.enable', {})
    driver.execute_script("console.profile()")
    
    # Do some actions on the page
    driver.find_element(By.XPATH, " ").click()
    driver.find_element(By.XPATH, " ").click()
    
    # Stop profiling now
    driver.execute_script("console.profileEnd()")
    
    # Get the performance metrics
    metrics = driver.execute_cdp_cmd('Performance.getMetrics', {})
    
    # Parse the bottom-up call tree
    for metric in metrics['metrics']:
        print(metric)
    
    
    driver.quit()

这将像这样打印所有指标
