Basic Website Speed Test
This utility measures the response time of a website. It calculates the Time to First Byte (TTFB), which is the time it takes for the server to start sending data, and the total time taken to download the full page content.
Modules Used:
- requests: To make HTTP requests.
- argparse: To handle command-line arguments.
time: To measure execution time.
The Code
Save this as site_speed.py.
import requests
import time
import argparse
def test_website_speed(url):
print(f"Testing speed for: {url}")
try:
# Start timer
start_time = time.time()
# Make request
# stream=True allows us to measure TTFB separately from content download
# We use a custom user agent to avoid being blocked by some servers
headers = {'User-Agent': 'Python Speed Tester 1.0'}
response = requests.get(url, stream=True, timeout=10, headers=headers)
# Time to First Byte (TTFB)
# This is roughly the time it took for the server to start sending data
ttfb = time.time() - start_time
# Read content to measure download time
# We don't need to do anything with the content, just consume it to measure throughput
