Http page response time.

You can log the time it takes to get the request at the LTM to the time the LTM gets the response from the server, but the time from LTM back to client is an unknown. On the browser end, you can use a tool like httpwatch to see the page load times. There are also tools like Gomez that inserts Javascript back to the clients that track this information, and then you can see how all your users by isp type, region, etc are performing to your different pages. Joe wrote a couple articles on implementing Gomez in iRules.
