It is my understanding from reading the documentation that setting the available memory only affects the P-1 factoring stage and not the main LL test. Is this correct?
The reason I am asking is because of a great difference that I have noticed in the iteration time of the LL test on my 2.2GHz desktop and my 1.0GHz laptop while running comparable sized numbers on both machines. I would expect to see the laptop taking a little more than double the iteration time of the desktop. Instead, I am seeing a 5x difference. The desktop is averaging 48 msec The laptop is averaging 250 msec Can anyone explain this? The available memory setting on my laptop is 64MB 24 hours per day, while my desktop is set at 192MB 24 hours per day. I have 1GB of memory on the desktop, so I can afford 192MB. The desktop is a Pentium IV while the laptop is a III. Could this account for the difference?
