Benchmarking

[eluser]Dam1an[/eluser]
I use

Code:

$this->benchmark->elapsed_time()

and it returns a decimal in the format #.####

This value will always be lower then that of yslow, as elapsed time is the time between receiving the request, and sending the rendered HTML page to the browser
The value with yslow will be when the request was made and when the page is loaded in the browser, so it will be elapsed time + latency * 2
