SonarLint greatly slows down Visual Studio 2015

1.3k Views Asked by At

I recently switched to Visual Studio 2015 (Community Edition) and installed SonarLint, hoping to synchronize my code analyzation settings with my Sonarqube. However, after installing the SonarLint integration in Visual Studio, I experienced a heavy slowdown of my IDE, inlcuding heavy stuttering and lagging. I have so far not even connected to my Sonarqube repository - the addon is simply loaded and - as far as I can tell - not used.

My specs are:

  • i7-2620M
  • 8GB RAM
  • Windows 10 x64
  • Visual Studio 2015 Community Edition
  • ReSharper Ultimate 2016.1
  • Productivity Power Tools 2015
  • GhostDoc
  • Code Contracts Tools

As soon as I disable the SonarLint plugin and restart Visual Studio, the IDE is reacting way smoother and stops acting sluggish.

Can anybody help me out with this?

The SonarLint Visual Studio extension analyses your code even if you don't connect the solution to a SonarQube project. So it's expected that some processing is going on. We've experienced high memory usage with Visual Studio 2015 Update 2, which is being or is already resolved by the Roslyn team.

SonarLint reports issues in the Error Window. You might want to have a look there, so that you see that SonarLint is reporting issues. All of our rules have IDs that start with a capital "S".
