I just tested my PHP app on Ubuntu 64bit, and found that all my php

confusing also runs a 64bit OS).
A page that would take up around 2.5 MB on the macbook, takes around
12 MB on the linux server.
Does anyone know what might be causing this?
All pointers are twice the size, same goes for the runtime stack.
Ok, so in the worst case scenario, I would expect it to require maybe
twice as much RAM then, but really, not more than maybe 10-20% more
since not all code is pointers. But 500% more? That seems a bit steep.
