But the proof is in the pudding.

My top (HPUX 11.0 64bit) does not have a shared column nor does my ps command show one.

I thought I would be sneaky and use this, but every single memory column showed the exact same information for all 3 processes. I thought this might mean since I wasn't creating or destroying variables they were sharing exactly the same memory (the child's memory space wasn't getting dirty), so I added some dummy code to do something similar to:

$dummy += rand;

No change in ps, top, or my custom perl code

so I decided to try and install Gtop as the article you mentioned referenced - I was not able to get to the site that it referenced, so I am back to square one.

How do I tell how do I profile how much total memory each process is using?

It isn't like I am expecting you to answer - just saying that it seems odd that there is no easy way to tell.

Cheers - L~R

I'm afraid you are on a sort of bizarre OS, so that will make everything harder. It is possible that HPUX has no copy-on-write feature, but that seems kind of crazy. I'd suggest asking your HP admin or HP's support.

The missing libgtop is kind of disturbing. I don't see any replacement for it handy.
