Can CPU throttling be controlled in Chrome's devtools using Python Selenium? If yes, what is the method to do so?
I noticed that the driver has a method called execute_cdp_cmd, which stands for "Execute Chrome Devtools Protocol command", but I am unsure of the specific command to use for CPU throttling.
It seems that in chromedriver 75, it is possible to adjust the CPU throttling rate.
## rate 1 is no throttle, 2 is 2x slower, etc.
driver.execute_cdp_cmd("Emulation.setCPUThrottlingRate", {'rate': 10})
PLEASE NOTE:
Version 2.38 did not seem to support execute_cdp_cmd(), whereas version 2.48 did. Chromedriver has also changed its versioning scheme to align with browser releases.
Upon quick testing, I managed to increase the throttle rate to over 200x, but encountered serious issues as a result. It is probably not advisable to go beyond 100x.
## Setting the throttle rate to 10 will result in no throttling.
driver.execute_cdp_cmd("Emulation.setCPUThrottlingRate", {'rate': 10})
This method is still effective and functional!
