For timing, you could look into:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Utilities/TimerLog
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Utilities/TimeStamp

Personally, I would use:
http://programmingexamples.net/wiki/CPP/Boost/Timer

ITK has a MemoryProbe:
http://www.itk.org/Doxygen/html/classitk_1_1MemoryProbe.html

(There is no example of it's use, but it should be similar to the
TimeProbe: http://www.itk.org/Wiki/ITK/Examples/Utilities/TimeProbe).
I'm sure you don't want to include ITK in your project just for this,
but I'm not aware of a VTK equivalent.
