Speeding up Intellisense on VS2015
You can use precompiled headers, it wont make it instant but should take ~1 second tops.
To do this:
1) Open your .sln
2) Project -> ProjectName Properties
3) Select either All Configurations or the ones you want to use
4) Configuration Properties -> NMake -> Additional Options
6) Wait until the 'working' symbol goes away, the intellisense should be much faster now.

This is a old post, but I thought I would comment my solution anyways. I found out that Microsoft Security Essentials (Windows Defender) slows down Intellisense and make it generally unusable or at least painfully slow. To solve the problem you can add an Exception processes to Security Essentials, which makes MSE not to monitor behaviour of those processes.
To add exception process, go to:
Microsoft Security Essentials -> Excluded processes -> Browse -> Find the devenv.exe or WDExpress.exe from your computer -> Press Add button -> Press Save Changes
I also added some other Visual C++ processes such as vcpkgsrv.exe and cl.exe as exceptions. After reboot intellisense ran so smooth I think I've had this problem all the time but it wasn't so severe I didn't really need to fix anything.
Hope this helps someone who is struggling with painfully slow Intellisense.
