Is Pagefile Necessary?

Which drive should the pagefile be on?

The simple rules in 2018 are now: Make sure you have lots of RAM, it’s pretty cheap these days.

Make sure you have fast disk, most likely an SSD.

Keep your page file on the C:\ drive with your Windows Operating System..

What is the optimal virtual memory size for 32gb RAM?

Microsoft recommends that you set virtual memory to be no less than 1.5 times and no more than 3 times the amount of RAM on your computer.

How big should my swap file be?

5 GB is a good rule of thumb that will ensure you can actually hibernate your system. That should usually be more than enough swap space, too. If you have a large amount of RAM — 16 GB or so — and you don’t need hibernate but do need disk space, you could probably get away with a small 2 GB swap partition.

What happens if I disable paging file?

Disabling the Pagefile Can Lead to System Problems The big problem with disabling your pagefile is that once you’ve exhausted the available RAM, your apps are going to start crashing, since there’s no virtual memory for Windows to allocate—and worst case, your actual system will crash or become very unstable.

Do you need a paging file?

1) You don’t “need” it. By default Windows will allocate virtual memory (pagefile) the same size as your RAM. It will “reserve” this disk space to ensure it’s there if required. That’s why you see a 16GB page file.

Do I need a pagefile with 16gb of RAM?

You don’t need a 16GB pagefile. I have mine set at 1GB with 12GB of RAM. You don’t even want windows to try to page that much. I run huge servers at work (Some with 384GB of RAM) and I was recommended 8GB as a reasonable upper limit on pagefile size by a Microsoft engineer.

Should I disable pagefile?

If programs start to use up all your available memory, they’ll start crashing instead of being swapped out of the RAM into your page file. … In summary, there’s no good reason to disable the page file — you’ll get some hard drive space back, but the potential system instability won’t be worth it.

Should I increase pagefile size?

The paging file can support system crashes and expand the amount of system-committed memory, or virtual memory, that a system can back. … Ideally, your paging file size should be 1.5 times your physical memory at a minimum and up to 4 times the physical memory at most to ensure system stability.

Do you need a pagefile with 32gb of RAM?

Since you have 32GB of RAM you will rarely if ever need to use the page file – the page file in modern systems with lots of RAM is not really required . .

Should I turn off pagefile with SSD?

In your case that’s an SSD which is several times faster than a hard drive but of course is pathetically slow compared to RAM. Disabling the page file would make that program simply crash. It would try to allocate more than it can and that would generate “out of memory” errors.

What happens if I delete pagefile sys?

Because pagefile contains important information about your PC state and running programs, deleting it could have serious consequences and tank your system’s stability. Even if it takes up a large amount of space on your drive, pagefile is absolutely necessary for the smooth operation of your computer.

Why is my pagefile so big?

sys files can take up a serious amount of space. This file is where your virtual memory resides. … This is disk space that subs in for main system RAM when you run out of that: real memory is temporarily backed up to your hard disk.

Will increasing page file increase performance?

Increasing page file size may help prevent instabilities and crashing in Windows. However, a hard drive read/write times are much slower than what they would be if the data were in your computer memory. Having a larger page file is going to add extra work for your hard drive, causing everything else to run slower.

Is pagefile bad for SSD?

Pagefile on SSD is fine. Maybe it’ll shorten the life of the drive a little, but for a good quality SSD it shouldn’t be significant. That said, you’d probably be better off finding a more efficient way to do whatever you’re doing that 32 GB of RAM isn’t enough.

Should pagefile be on C drive?

The page file is still used and will continue to be used regardless of how much RAM you have. Under XP and earlier (and I THINK this holds true in Windows Vista, 7, and 2008) the pagefile allows memory dumps for debugging but must be on the C: drive for them to work.
