Reusing objects will always going to be faster. If memory is not being allocated, GC never runs.

Look what happened to Minecraft when they stopped caring about allocations: http://what.thedailywtf.com/t/optifine-modder-rips-the-minec... It's allocating 150 MB/second. It's now much slower than it was before.

What's wrong with MSBuild/XBuild?

I just type "msbuild" (or press F5 in VS) and I get result .exe file in 0.2 second. On Linux I type "xbuild" and it's the same. You can use Visual Studio without even knowing msbuild exists. Just occasionally a pre-build or post-build script needs to be added.

Makefiles, Gradle or CMake are much slower and very complicated.
