I'm writing a piece of code for a customer that forks a copy of itself.
here is the (edited) output of top:
  
PID   USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME COMMAND
29943 dshahin    0   0  4808 4808  4476 S       0  0.0  1.8   0:00 MIO2
29940 dshahin    0   0  4792 4792  4468 S       0  0.0  1.8   0:00 MIO2
my question is regarding the 'SHARE' column.
Does this mean that additional process only uses 'SIZE - SHARE' kilobytes of new memory? The customer is concerned (rightly so) about over-utilizing system resources. They might run many copies simultaneously, will each only eat up 'SIZE - SHARE' k of 'fresh' memory?

I want to be able to tell them there is a 5 meg initial hit, but each new process only uses less than 1meg new memory? Am I lying?:)

A lot of this memory usage is from IO::Socket::SSL, my boss wants me to write it in C to bring down the memory usage, but it will take much longer and be more prone to errors.

What is a better solution?

Any general memory-saving tips are appreciated.
