I need to find the load time of a website that I am currently building. I have hosted the site locally. How can I find its load time using python or javascript? I tried the following code, but I think it is for response time.
from time import time
from urllib.request import urlopen
stream = urlopen('https://01c92730.ngrok.io/index.html')
cream = urlopen('https://01c92730.ngrok.io/Webpage.html')
start_time = time()
output = stream.read()
end_time = time()
stream.close()
print(round(end_time-start_time, 3))
start = time()
output = cream.read()
end = time()
cream.close()
print(round(end-start, 3))`
Just put var start = Date.now() at the start of the page and (Date.now() - start) at the end of the page to get the loading time.
Case 1# without loading a library
<doctype html>
<html>
<head>
<script type="text/javascript">
var start = Date.now();
</script>
</head>
<body>
<script type="text/javascript">
document.write("Page load time " + (Date.now() - start) + " milliseconds");
</script>
</body>
</html>
Output: Page load time 0 milliseconds(Sometimes 1 millisecond)
Case 2# loading jquery library
<doctype html>
<html>
<head>
<script type="text/javascript">
var start = Date.now();
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
document.write("Page load time " + (Date.now() - start) + " milliseconds");
</script>
</body>
</html>
Output: Page load time 24 milliseconds( sometimes 22,23)
