Selenium Webdriver für Chrom verlangsamt sich mit jeder Schleifen -Iteration in Python ⇐ Python

[Anonymous]

Ich möchte 50 Gruppen (Site -Abschnitte) mit jeweils 100.000 Seiten -IDs durchlaufen, aber Selen wird mit jeder Iteration langsamer. Was könnte das Problem sein? < /P>

Code: Select all

chrome_driver_way = './chromedriver/chromedriver.exe'
options = Options()
options.add_argument('--no-sandbox')
options.add_argument('--headless')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--disable-gpu')
options.add_argument("--disable-extensions")
options.add_argument("--disable-infobars")
options.add_argument("--log-level=2")
options.add_argument('--ignore-ssl-errors')
options.add_argument('--ignore-certificate-errors')

for group in groups:
texts = [None] * len(ids)
with webdriver.Chrome(
executable_path=chrome_driver_way,
options=options
) as browser:
start = time.time()
for n, id in enumerate(ids):
browser.get(url.format(id))
text = browser.find_elements(
By.XPATH, '//div/div/div'
)
texts[n] = text[0].text
if n != 0 and n % 100 == 0:
print('group {}: IDs {}-{} processed in {} s'.format(group, n - 100, n, time.time() - start))
start = time.time()
del text
