Visual Studio 2013/2015 Idle CPU usage

Question

I\'m currently evaluating Visual Studio 2015 RC. I\'ve noticed when running the IDE, The Visual Studio 2015 process is constantly at around 25% CPU usage. Even without a project

Answer 1

In my case it was either the Roaming Extention Manager or most probably the azure worker role project in my solution. If you have one of these try unloading it and restart visual studio. I can reproduce it but I don't know why it happens.

Answer 2

In my case disabling Telerik ASP.NET MVC Extension solved high CPU issue.

High CPU load started on solution load and didn't drop (40% with one, 80% with two solutions) until VS was closed or even sometimes after (had to kill the process).

Tools->Extensions and Updates->Installed, find the extension and click 'Disable'.

Answer 3

In my case, The .suo file in Visual Studio was the culprit. Deleting it fixed my issue.

Answer 4

I run resharper, turned that off and turned off the Microsoft Git provider and still had high CPU issues, devenv.exe would also run after close... until recently.

It appears VS 2015 Update 2 has resolved these issues!

Answer 5

In my case, the culprit was Node.js tools for Visual Studio. I had v1.1.2 installed and the cpu was constantly around 25-40%.

A switch to Node.js Tools v1.2 RC resolved the problem completely after an initial high load that went away in a couple of minutes.

I've noticed also that when running and stopping a debug episode on the local server, if the page is still open in the browser, VS will continue to run at high CPU. Closing the browser page stops this.
