Paging is going to happen no matter what and some applications are written with that in mind. I would recommend against turning it off. Especially since it has to happen anyway.
How can an application be written with the page file in mind? It is a HW mechanism: If a page fault occurs, which is a HW interrupt, the MMU responds by retrieving the appropriate page (which depends heavily on the type of HW involved... LBA, indexed memory, etc).)
How is the OS controlled page file a hardware thing? Paging is up to the OS my friend, hence why Windows and Unix have two very different takes on paging and "swap" space.
I'd further like to know if I have 6 GB of physical ram why would I see 2.5 GB ram used and a 2.5 GB page file? Shouldn't the hardware know better? That there is plenty of ram space free?
I think we both know that this 1.5 deal has been around since 95/NT. To be clear, I chose XP because of the shift in these things...yea..HDs became bigger, RAM more readily available...and you're right with TB drives at 8 Gigs of RAM on one's machine...why sweat this.
Agreed. Gotta speak to the LCD though, we know it has been kind of a best practice/standard for a while. Not everybody might though. I don't think we are to the point where the LCD can turn off the page file. Psymonkey might be able to, but I can't say for sure.
Does having the page file on a considerably slower drive degrade performance? Right now it's eating an awfully large percentage of the space on my 128gb RAID 0, 6gbps SSD boot array. If I move it to the good old 2TB 7200RPM 3gbps drive, am I kicking my own self in the pills?
If not then it's no big deal at all. If there is a performance hit, do I really nearly 20GB dedicated to the page file on the system drive?
Will it be slower? Sure, are you going to notice it? No way. When a page fault occurs things are already going to be put in a holding pattern because the memory page has to be retrieved from disk and loaded into physical memory (and likely something else has to be paged out).
Try turning it off and see what happens?
