Overview: Viewing application page load times
This implementation describes how to display the length of time it takes for application web pages to load on client-side browsers. This information is useful if end users report that an application is slow, and you want to determine the cause of the problem. You can view page load times on the Analytics charts only if the Analytics profile for the web application is configured to save statistics concerning page load time.
The system can collect page load times only for clients using browsers that meet the following requirements:
- Supports Navigation Timing by W3C
- Accepts cookies from visited application sites
- Enables JavaScript for the visited application sites
Viewing application page load times
Before you can view application page load times, you need to create an Analytics
profile that is logging statistics internally on the BIG-IP
system. In the profile, the statistics-gathering configuration must have Page
Load Time selected as one of the collected metrics. The Analytics
profile also needs to be associated with one or more virtual servers, or an iApps application service.
You can view page load times on the Analytics charts. Page load time
is how long (in milliseconds) it takes from the time an end user makes a request for a
web page, until the web page from the application server finishes loading on the
client-side browser.
Note: End user response times and latencies can vary
significantly based on geography and connection types.
Tip: If you are concerned about maintaining a high level of user experience
and productivity, you can configure the Analytics profile so that it sends an alert
when the average page load time exceeds a number of milliseconds for some period of
time.
