Hello Everyone,
After reading Practical mod_perl's section on Improving Performance with =
Shared Memory and proper forking a bit, I'm wondering if I can setup a =
means for testing what is shared and when it becomes unshared in my =
memory usage.
I can't seem to currently get GTop installed on my OS X box (I'm sure =
that will get resolved shortly.)
So, I was wondering if anyone has come up with an alternative to =
determine a way of testing or debugging when memory goes from shared to =
unshared in the mod_perl environment?
I notice in my processes (using top) that there are several processes =
that look like they have the same memory maps with regards to shared vs. =
unshared memory, then there is the root, and one child that has it's one =
shared and unshared memory allotment. It usually starts with less shared =
memory than the rest, but on every restart the memory usages change so =
that the shared amounts change with each restart, sometimes higher, =
sometimes lower.
I'm wondering if there is a way to see under the hood so to speak to =
determine what is being shared and what is not in each child process.
Obviously, single user mode type debugging is out.
Any suggestions?
Thank you,
