I've rechecked it and I rebuilt the project file from scratch. Set the 
_SECURE_SCL define again. Optimizing, release mode. This does not help.

Then I compiled from the commandline. This helps: I now get about the 
same performance (slightly slower in some cases). So at least we know 
that the compiler is OK. It is somewhere in the project file...

Anyway, it's working. Checked some things more, removed the manifest 
file, changed to multithreaded (without DLL). Same effect. It might be 
something in my environment, having 2005 and 2008 together, maybe the 
2008 steals some settings automatically from 2005 (while in the command 
line it is OK).
