Upgrade the chromedriver(>2.25)/chrome browser(>55.0) on your MAC to remove the empty data; tab.
You can use threading or multiprocessing to speed up the process.
from multiprocessing import Process
import os
import selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver =webdriver.Chrome('/usr/local/bin/chromedriver')
driver.get("http://msn.com")
def func1():
print 'launching: MSN'
driver.execute_script("window.open('http://www.msn.com');")
def func2():
print 'launching: CNN'
driver.execute_script("window.open('http://www.cnn.com');")
if __name__ == '__main__':
p1 = Process(target=func1)
p1.start()
p2 = Process(target=func2)
p2.start()
p1.join()
p2.join()
def runInParallel(*fns):
proc = []
for fn in fns:
p = Process(target=fn)
p.start()
proc.append(p)
for p in proc:
p.join()
runInParallel(func1, func2)
Depending on how many CPUs you have, the load of the machine, the timing of many things happening in the computer will have an influence on the time the threads/process start. Also, since the processes are started right after creation, the overhead of creating a process also has to be calculated in the time difference you see.
