Visual Studio 2012 slow compilation, high internet usage

Question

When I compile my project in VS 2012, it takes forever (minute or 2). I have noticed, in my task manager, that the "System" is using internet connection heavily during the compilation.

I have tried disabling the symbols loading.

So far only thing that helped was me disabling my Local Area Connection.

Any idea what could be causing this?

I have also noticed that mine has increasingly gotten slower — amadib, Oct 05 '12 at 21:36
It seems that the XAML designer is also very slow and is downloading something.. — Miro Bucko, Oct 22 '12 at 16:17
Th only quick fix I use for now is disabling and enabling my Local Area Connection which interrupts the download and allows the compilation to continue.. — Miro Bucko, Nov 07 '12 at 18:53
I had an async service that was running on my machine that was for some reason slowing down my compilations. Disabling or stopping it appears to have fixed it. — amadib, Nov 12 '12 at 21:13
Did you check with wireshark (network trace) what is being downloaded? — Werner Henze, Dec 07 '12 at 14:40
Which Edition of VS2012. Also how many number of project are there in your solution and what's type of project are there in it. Also what's your's operating system — Kamran Shahid, Dec 11 '12 at 15:05
Have you got an Entity Framework project/model in the solution? — Mike Simmons, Dec 11 '12 at 15:24

Could it be caused by extension or addin you have installed? For example, NuGet will download missing packages during build if they're not there.

Try to monitor your network with application such as WireShark and it may point you in the right direction.

You may also run Visual Studio with /Log parameter and see if there is anything logged in the activity.log.

Finally, you can set build output to Diagnostic from Tools | Options | Project and Solutions | Build and Run and see if there's anything unusual there.

My project no longer takes any extra time to compile.. very strange. Maybe some update has fixed it. Also the build output is very useful. — Miro Bucko, Dec 17 '12 at 12:23

This may have something to do with VS checking for revoked certificates. Have a look at this post...

How to stop SSIS from "Phoning Home"

I find it has significantly improved VS performance.

I guess you have enabled the getting symbols from Microsoft servers. Go to visual studio options -> debugging -> Symbols and check your settings.
