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.
