How to calculate response time in Django Python

Question

I am new to Django Python. Please advise how to calculate a response time from the moment where the user input the search criteria until the relevant information are loaded/disp

Answer 1

Here’s the class that does the entire thing

import time


class StatsMiddleware(object):

    def process_request(self, request):
        "Store the start time when the request comes in."
        request.start_time = time.time()

    def process_response(self, request, response):
        "Calculate and output the page generation duration"
        # Get the start time from the request and calculate how long
        # the response took.
        duration = time.time() - request.start_time

        # Add the header.
        response["X-Page-Generation-Duration-ms"] = int(duration * 1000)
        return response

That’s all there’s to it. Just store the time when the request comes in, and retrieve it later.

To install the middleware above, just add it to your settings.py:

MIDDLEWARE_CLASSES = (
    'project.stats_middleware.StatsMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    ...
)
