Description:
 Enter the demo URL below
Step1:  Measure response times and plot results
Change the value of num_trials or add queries to item_types as needed.
You can also add output_path='/your/path/file.txt' parameter to check_response_time() if you want to specify it; otherwise it will save check_response_time.txt on the desktop. Add alt_format=True to output an additional, reformatted output log.

Explanation: Measure response times and plot results
Change the value of num_trials or add queries to item_types as needed.
You can also add output_path='/your/path/file.txt' parameter to check_response_time() if you want to specify it; otherwise it will save check_response_time.txt on the desktop. Add alt_format=True to output an additional, reformatted output log.
