Check whether your current settings and exponents are reaching the bounds required to retire the P1 task from the database. Repeated P1 with increasing bounds is wasteful. Aim to finish the task with sufficiently high bounds, so no one else has to. If that is not practical, then P1 is not a good work type for the system involved. Note though that lower bounds than the guidelines may be offset by higher TF than usual guidelines in some exponent cases in the database.

It looks like I have 16GB of RAM, so I changed it to 1. Should I go higher?

Yes. The only part that uses a significant quantity of memory is the second half of the P1 factoring attempt that is made before a primality test. (RAM speed is very important for big FFTs but quantity doesn't matter other than through its correlation with the number of sticks for RAM channels.) If your primary goal is to PRP, then you will probably never even notice the brief window when P1 uses it's max allocation. Turn it up!!!

Some people count sheep if they can't sleep. But sheep = lamb chops = hunger, not sleep. So in high school, I decided to count pi instead. When I couldn't sleep, I'd go 3,1,4,1,5,9, etc., instead of 1,2,3,4,5, and so on. On some nights, I got up to the Feynman point: https://en.wikipedia.org/wiki/Six_nines_in_pi . On really sleepless nights, I counted up to 900950 digits, but I don't think I ever went beyond the 1,000 digit mark. College soon came around, and those nights spent counting pi were replaced by nights thinking of finals, projects, internships, and bills. It's been well over a decade since I last counted pi, but reading this made me curious to see how much pi I had in my long term memory. The answer was 110 digits. Strangely enough, I remember the string "5058223172", but have no idea what numbers come immediately before or after that without looking it up.
