Visual Studio 2010: very slow web applications debugging!

Question

I recently installed Visual Studio 2010 (Ultimate edition, final version released in April), and found that debugging a web application bec

Answer 1

Try removing the localhost from the list of trusted sites in IE security settings.

For me it solved the problem of slow JavaScript debugging in VS 2010. It may work for you if you have added 'localhost' (or any other domain name you use for local development) to the trusted sites list, like I did.

Answer 2

What is expensive too sometimes is debugging the JavaScript libraries you are using or developing.

Checking the option "Don't open a page" in the project property window allows you to debug the web application without debugging JavaScript. You simply have to open the web application in your browser manually.

In some circumstances debugging JavaScript can break the responsiveness of the debugging process and if you know that your concern is with the .NET debugging, you can make load time faster that way easily.

Answer 3

There is another trick you can do:

1) Go to (Ctrl + Alt + Del) Task manager > Processes

2) There are 2 main processes for visual studio debugging, 1)devenv.exe 2) WebDev.Webserver40.exe (Or similar).

3) Right click on each of the bove processes > Set Priority > Real Time. Click Ok in the message Box.

Speeds up debugging dramatically!.

After incredibly slow debugging for months I finally discovered the cause (even after disabling intellitrace).

It turned out to be PC Tools internet security -> IntelliGuard -> 'Behaviour Guard'

This is a hips like protection system that monitors the 'signature' of system operations

I disabled this feature and wow what a speed difference - 'stepping into' lines of code in debug now has almost zero delay. I re-enabled Intellitrace and can use it with only a very slight speed hit.

I tried a lot of things and the only way to solve it was the swax solution 'Delete all breakpoints'
