Do you see the spike as soon as you start Apache but before you even try and access your Python web application, or does it only occur when you first access the Python web application? If the latter, have you tried a simple 'mptest' example as per mod_python documentation and does it exhibit the same problem? Ie., eliminate it being anything to do with Django, in which case you would be better off asking on the mod_python mailing list. Other things to look at are whether your Python has been built to use shared libraries or not. If it hasn't and your mod_python.so is large because it incorporates Python library, you will potentially be stuck with private copy of Python library in every process and if you are running with minimal memory on your system with lots of prefork processes, you may well be running out of main memory and the box is busily swapping to disk. How big are your Apache child processes on initial startup and then subsequently after you have accessed your Python web application? How big is your mod_python.so module file.
