Summary: 

Try the following to decrease your paging while the program is running.

	Increase wsquota and wsextent and wsdefault to high numbers.
	Increase the maximum ws parameter in sysgen (I don't know the name)
	Modify the program to lock itself into memory.
	Increase the size of the free list and modified list so that
		some of those page faults are not real faults.
	Increase the initial size of your stack if your program
		uses a lot of stack.

However, You can't get rid of all page faults. When a program is run,
it is not loaded into memory. It simply has the page table set up
as showing all the pages as being paged out. The pager then loads
the program as it is needed.

To see how much is real paging, try mon page. If not read or write page
values appear, all of your paging is fake.
