I believe that you built osg without optimization.
When building without optimization you get what you ask for. Unoptimized code
that takes hours for the cpu intensive jobs like culling. That is also what
the stats show ...
Configure osg with ist's new build system as a Release version. Or provide
CMAKE_CXX_FLAGS and CMAKE_C_FLAGS on the command line of cmake.
I run cmake with something like
cmake -D CMAKE_CXX_FLAGS="-O3 <and some more>" \
-D CMAKE_C_FLAGS="-O3 <and some more>" \
-D CMAKE_VERBOSE_MAKEFILE=TRUE .....
Please try ...
Greetings
Mathias
