Hello all!

I noticed some performance issues with an update of OpenCV 2.4.3 to 2.4.5 and higher (also current git repository) in my project. I was wondering if this is a known issue or if anyone else can confirm this? Here are some specs: * win7 * Visual Studio 2010 or 2012 * C++/CLI * 64-bit

The problem is reproducable for me with self compiled and precompiled opencv libs. There was no other changes in code. I mainly use the SIFT Method. Runtime is about 2.5-times as before the update. Thank you for all your help!
