My ASP.NET site is running slow, and I decided to troubleshoot it to figure out what to tackle first.

I've used Fiddler2 to see where the bottleneck is, the results DO NOT MAKE ANY SENSE!!!

Please see below and let me know what am I doing wrong?

When I request an image from my local server, I get the following from Fiddler:

ServerGotRequest:      17:30:05.963
ServerBeginResponse:    17:30:06.042

When I request that same image from a client (different network, many miles apart), I get the following from Fiddler:

ServerGotRequest:      14:29:05.723
ServerBeginResponse:    14:29:06.383

That's a HUGE difference, and according to Fiddler's site,

Can i find out how long the server needs to process my request ?

(ServerBeginResponse - ServerGotRequest) is probably what you want.

THIS DOES NOT MAKE ANY SENSE TO ME.

Why would it take THE SERVER any more time to process the remote request over the local one? This timeframe does not include any network traffic from what I can tell from Fiddler's site. Any ideas?

Maybe I'm just dense but I see roughly half of a second difference. How is that huge? Or am I reading the times wrong? – joeqwerty Aug 12 '10 at 23:00
that's just ONE IMAGE, when you have 20 of them, it all adds up. I think you missed my point though - why would there be ANY time difference ??? – roman m Aug 12 '10 at 23:06
Well personally I don't think you can expect a request for the same image to take exactly the same time, every time. Have you run the test more than once locally and remotely and compared the results. Are the results exactly the same every time? – joeqwerty Aug 12 '10 at 23:13
let me rephrase, I'd expect the time difference to vary, but not 6x difference. The image example is oversimplified so that I can get some meaningful answer to the question. And YES, I've tested multiple times and the difference is consistent (though not exactly the same every time) – roman m Aug 13 '10 at 0:11
