Visual Studio started working slower than usual, and after checking for add-ons and doing a repair, it's just as slow. I used process monitor to check what was going on, and found that a lot of stuff is going on related to SQMClient, which - as far as I understand, is part of Microsoft's customer feedback program. I'm not participating in the program (I've double checked). Still - process monitor tells me that VS does a lot of stuff related to SQMClient:
It keeps repeating this over and over. Do any of you know why VS might do this, and if this is the reason behind the slow behavior?
You might have extensions installed that slow Visual Studio down. For help on managing extensions to improve performance, see Change extension settings to improve performance. Similarly, you might have tool windows that slow Visual Studio down.
No. No app will slow down your computer unless you use it. Any app that you invoke will have an effect on RAM and processing, so they all “slow down” a computer. If you have enough resources (RAM, SSD, fast processor), you will not notice the effect.
This is mainly because Visual Studio has lots of components, extensions and tools.
This problem may happen if there is a number of SQM reports, saved in the user profile. When unable to connect to internet Visual Studio stores SQM files in %userhome%\AppData\Local\Microsoft\VSCommon\<vs_version>\SQM
. The number of files grows continuously and it can get to many thousands. When this directory is cleaned or removed, Visual Studio sped up significantly.
