Hi, I suffer very strange problem: osgDB::readNodeFile() method is dramatically slow when loading *.obj files and is called from Qt4 application. The tiny test Qt project is attached. For every other format I ever tried everything work flawlessly.
I also found that the cause is in Q(Core)Application creation before calling readNodeFile(). If you comment it out, everything is fine. If you uncomment it back, the problem returns. Here're some timing results: - without QCoreApplication construction Code: $ time ./osgtest real 0m0.706s user 0m0.344s sys 0m0.072s - with QCoreApplication construction Code: $ time ./osgtest real 0m46.886s user 0m46.479s sys 0m0.216s Did anyone notice something like this? I think it can be because of some threading problems but can't still evaluate. Thank you!
