Project now utilizes the /MP compiler switch to perform parallelized builds. The number of parallel builds performed is determined on a per-machine basis based on available logical CPUs. Long term this will provide the best performance output to code maintainability ratio compared to just enabling precompiled headers. Using my personal machine (8 cores), I got the following timings (Debug configuration): * Normal build : 89 seconds * Multi-processor build : 28 seconds * PCH enabled : 27 seconds Note that the multi-processor build timings can be further reduced with proper dependency management and removal of existing precompiled header file (precompiledHeaders.h). Specific Changes: * Precompiled header support disabled (not compatible with /MP flag). * precompiledHeader.cpp deleted. * Solution File added. * Minimal Rebuild (/Gm) disabled (ignored when /MP is on). precompiledHeaders.h still exists because it contains a ton of inclusions required by lots of files. A second and less trivial cleanup will involve removing the precompiledHeaders.h file and individually correcting and satisfying dependencies in each source file in the code base.pull/90/head
