Description
Some commits made by mmlr in December 2011 resulted in poor performance when Haiku is run in virtual environment (possibly with disabled hardware virtualization).
We even provided custom images built with KDEBUG_LEVEL=0 for some CGI students, otherwise Haiku was simply too slow for them in VBox.
Quoting Michael from IRC:
If it was introduced with the allocation tracking commits then it'd be a side effect or bug introduced, as the main feature isn't enabled even in KDEBUG.
Instead of searching through the commits you could also disable the features one by one in the kernel_debug_config header and see which one is responsible.
They can generally all be individually turned on and off.
