first of all, thanks a lot for this great advantage piece of software :-)
I am a little bit stucked with my problem, so maybe I've missed something.
A project, i am currently working on - running "locally" in a VirtualBox, bridged network. (PHP / Yii Framework) When I load a page, there are access times around 550ms - 2,5s. This does not really depends on a keep alive or a new connection. Page generation time is mostly around 200ms.
Now when I start Fiddler, the first page load after that is around 20-40ms more than page generation time and all next loads as fast as the first - not much more than 300ms. I can wait 2 minutes and load a new page, and I get the same results.
That is really awesome, but I don't think, I can convince my customers to install Fiddler :-))
I have read a lot about that problem - the keep alive problem is excluded (I also disabled the options in Fiddler) Firebug marks it as "waiting time" without more info, when Fiddler is unactive.
