Version: 0.15.4669 (Git)
Branch: releases/FreeCAD-0-15
Hash: d8bbbc1d1d111bd600025b2ba83f41b7353e3790
Python version: 2.7.8

First, I tried to install it on top of my old FreeCAD 0.14 64-bit (out of curiosity). Not unexpectedly, it failed to run with an error. I didn't write it down, but it was something about "Application attempted to load a library in an incorrect way".
OK, clean install. All right. Runs. BUT! it is slow as a dead cow. It works almost as slowly as a debug build. Why?!
EDIT.
for example, my build takes 8.4 seconds to start, while the installed one takes 22 seconds!
