wd: I'm using the "Release" version ... i don't use the debugger at all. I'm investigating drive_local.cpp now and i'll try the LOG_MSG() with timing ...

Qbix: seriously ? I designed the LOG()() class so that they should be optimized out in release mode. At least that happened last time I checked the compiled code (compiled with mingw though) Yes, but a litlle bit ... Since it's around 1000 files it call LOG for each file ... (And i think you're …
