performance tuning ask for advice

Question

Hello everyone,

I found when I turn off (un-select) automatically detect proxies setting in Internet Options, my application (which involves a lot of Http based network communication) performance will boost a lot. Now I want to prove that performance issue is actually caused by automatically proxy detection.

Any ideas from debugger or from other points to prove?

thanks in advance, George

Answer 1

You could use wireshark to analyze your theory.

Answer 2

You can try the Microsoft Visual Round Trip Analyzer (VRTA). Run one series of tests with automatic proxy detection on, then the same series with it off. It's important to do multiple tests and take the average across the tests, in order to account for usual network randomness.
