Sorry about that. Frankly, this thread became too voluminous for me to really follow. Firebug can help you with this. Its Net Tab displays a line (and the tooltip when you hover your mouse over it tells you the exect metric) for the "DOMContentLoaded" event. Even though this is a non-standard Mozilla Feature (if I'm not mistaken), it is a good enough indication. It tells you when Firefox was able to start rendering the page. I tend to further simplify and propose that this is close to the time it takes to load the HTML content, typically the generated content from PHP, ASPX or whatever is at work on the server. While other items like stylesheets will also be required by the browser, those can be cached very effectively, so I hope it is safe to disregard them. But I cannot stress this enough: these are all estimates only! > Also, how does a tester calculate the page response time using load balancer > logs? *If* your webserver is behind a Loadbalancer (your will have multiple web servers in such a setup), your LB software may or may not be able to log accurate Webserver respnse times. As Deepak pointed out, the client will see longer times due to network latency, but I disregard those in all load tests I do (I run Jmeter in the same subnet, as I'm not testing the internet link, only the servers). > And what are those reverse proxy logs he was talking about? The loadbalancing software is a special case of a reverse proxy. If you don't use multiple webservers, you may still want to use nginx, apache or any of their ilk to do smart things like caching. In both cases (loadbalancing or simple reverse proxy), all requests pass the proxy and their timings can possibly be measured there. Stop writing so much, I cannot possibly read all of it ;-) Cheers, Felix --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
