How to overcome the lagging of typing in the editor while using ReSharper?

Question

I'm using Visual Studio 2013 with ReSharper 9 on a quite strong computer (16GB RAM, Core i7 CPU, SSD, etc.). Still I experience heavy delays and laggings during typing for example in a C# or Razor source file.

I've noticed that every time I hit a key, the processing immediately starts, and context actions, offering rename refactorings, autocompetion immediatley shows up in the editor. It would make sense to delay these stuff for example so that all of this processing would start only when I finish typing and have some amount of quite milliseconds.

I've browsed through the settings for the third time now, but could not find anything related. Is there anything like this? If yes, where? If no, what else could I do to overcome this lagging? It's really annoying and I don't quite understand it. I can't beleive that such a computer is still not enough.

Disable Bing Developer Assistant extension if you have it by going to 'Tools -> Extension And Updates'. Disable the Microsoft Git Provider Plugin by going to 'Tools -> Source Control -> Then setting the Plug-In ComboBox to NONE.'

The above has helped me and has improved performance on my PC. Hopefully it will help you too.

You shouldn't be seeing a lag while typing. I'd suggest disabling other extensions to see if there's a clash - something that ReSharper doesn't like being installed at the same time. Alternatively (or better yet, as well) you can profile Visual Studio to see what's going wrong. Go to ReSharper → Help → Profile Visual Studio, and ReSharper will download the profiler, attach to Visual Studio and start to gather info. Once you've demonstrated the problem, click "Get snapshot", and ReSharper will save the snapshot and add it to the dialog as an attachment. You can then describe what you were doing and submit the snapshot and description to the dev team.

I'd also suggest downloading the latest build - the 9.2 EAP has just started, and contains a number of fixes that might help performance under certain circumstances.

Also, what are you typing in - what language, what size file?
