Page Fault rates
 

Hello;
I am not sure if this is the right spot to post this but here goes...

I want to know how I calculate the highest acceptable page-fault rate not exceeding 100 nano's if I have a demand paging system with the following knowns:

EAT - 50 nanos
Valid page in page table
Page fault service time (PFS) = 5 milli

Re: Page Fault rates
 

The Formula is
EAT (Effective Access Time)=(1 – p) x memory access time + p (page fault overhead + [swap page out,if needed] + swap page in + restart overhead)

Where p is Page Fault Rate
0<= p <=1

Page Fault time = page fault overhead + [swap page out, if needed] + swap page in +
restart overhead

I think with this formula u can calculate
