Hi All
I just tested my PHP app on Ubuntu 64bit, and found that all my php
scripts would consume about 5x more RAM memory there, compared to
how much they use on my macbook pro (which to make things a bit
more 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?
Thanks

Have the two installations been compiled with the exact same options/
extensions? Are the exact same extensions being loaded on both
installs?
You raise a very good point, and I think I might have been a bit hasty
comparing my macbook pro against ubuntu, which both use different
extensions and configure options.
Now, I just tested the exact same setup on another Ubuntu machine,
with the same everything except for that its 32bit instead of 64bit.
Result (loading the same page on both machines):
32bit: 7640128
64bit: 14155776
So the 64bit version consumes roughly twice the amount of ram as the
32bit version. Makes sense, considering the pointers and runtime stack
that was explained in this thread.
Thanks
Alec
