What is the bandwidth requirement for Project Web Access (PWA)? How long does it take to load specific PWA pages? What are all HTTP calls for each component that make up a page? Why is the page taking so long to load? etc… If case you did not know, the easiest way to gather this information and answer the previous questions is to use this free tool called Fiddler.
What is Fiddler?
Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language.
Fiddler is freeware and can debug traffic from virtually any application, including Internet Explorer, Mozilla Firefox, Opera, and thousands more.
