What is meant by "significcantly less than the address space limit"?

On Tru64 v5.1a systems with 8GB memory running internet servers and oracle
database, I'm trying to increase various memory parameters, going thru
tuning docs, on both:
        [max_]per_proc_stack_size
and [max_]per_proc_data_size

the documentation says:
  "Choose values that are significantly less than the address space limit"

What do they mean by "significantly less"?? Half of it? 3/4 of it? That's
a very relative sort of statement.

                                Defaults Recommended
                                                        (for internet server)
max_per_proc_stack_size = 33,554,432 bytes
per_proc_stack_size = 8,388,608 bytes
max_per_proc_data_size = 1GB 10GB
per_proc_data_size = 134,217,728 bytes
[max_]per_proc_address_space = 4GB 10GB

How can max_per_proc_data_size be recommended at 10GB, yet still
"significantly less than" max_per_proc_address_space" which is also
recommended to be set to 10GB??????????????


Huge TIA for clarification!
