Visual Studio Multiprocessor Settings
If you have an multicore processor with 4 or more cores, than you possible want to use all of it to build Visual Studio Solutions. For big projects it's very usefull to build with a maximum number of cores on system.
To Get the number of cores, you can look at Taskmanger -> Ressources.
You have to place the number of cores here: Menubar->Tools -> Options -> Projects and Solutions -> Build and Run -> maximum number of parallel project builds
Now all Solutions should build faster.
It dependes on project structure and thier dependencies how much faster it builds.
