Do not disable the swap file It is not just for when you run out of memory. There is no direct performance gain in turning it off, windows only reads from it when it needs to, it writes to it all the time so it is ready whenever it is needed.

Is swap really necessary?
Why is swap needed? … If your system has RAM less than 1 GB, you must use swap as most applications would exhaust the RAM soon. If your system uses resource heavy applications like video editors, it would be a good idea to use some swap space as your RAM may be exhausted here.
Is using swap memory bad?
Swap is essentially emergency memory; a space set aside for times when your system temporarily needs more physical memory than you have available in RAM. It’s considered «bad» in the sense that it’s slow and inefficient, and if your system constantly needs to use swap then it obviously doesn’t have enough memory.
Does disabling page file increase performance?
Myth: Disabling the Page File Improves Performance
People have tested this theory and found that, while Windows can run without a page file if you have a large amount of RAM, there’s no performance benefit to disabling the page file. However, disabling the page file can result in some bad things.
Is it OK to 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.
Why is swap usage so high?
your swap usage is so high because at some point your computer was allocating too much memory so it had to start putting stuff from the memory into the swap space. … Also, it’s ok for things to sit in swap, as long as the system is not constantly swapping.
What happens if swap space is full?
3 Answers. Swap basically serves two roles — firstly to move out less used ‘pages’ out of memory into storage so memory can be used more efficiently. … If your disks arn’t fast enough to keep up, then your system might end up thrashing, and you’d experience slowdowns as data is swapped in and out of memory.
What happens when you run out of swap?
With no swap, the system will run out of virtual memory (strictly speaking, RAM+swap) as soon as it has no more clean pages to evict. Then it will have to kill processes.
Is swap memory bad for SSD?
If the swap was used often, then the SSD may fail sooner. … Placing swap on an SSD will result in better performance than placing it on an HDD due to its faster speeds. Additionally, if your system has enough RAM (likely, if the system is high-end enough to have an SSD), the swap may be used only rarely anyway.
Why is swap being used even though I have plenty of free RAM?
If there is a lot of «pressure» to allocate new memory, then it will increase the chances some will be swapped to make more room. … If you reduce the swappiness, you let the amount of cache memory shrink a little bit more than it would otherwise, even when it may really be useful.
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.
Is it safe to 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.
Should pagefile be on C drive?
You do not need to set a page file on each drive. If all drives are separate, physical drives, then you can get a small performance boost from this, though it would likely be negligible.
How do I permanently disable swap?
Identify configured swap devices and files with cat /proc/swaps . Turn off all swap devices and files with swapoff -a . Remove any matching reference found in /etc/fstab .
- run swapoff -a : this will immediately disable swap.
- remove any swap entry from /etc/fstab.
- reboot the system. If the swap is gone, good. …

Should I change my paging file size?
Increasing page file size may help prevent instabilities and crashing in Windows. … Having a larger page file is going to add extra work for your hard drive, causing everything else to run slower. Page file size should only be increased when encountering out-of-memory errors, and only as a temporary fix.
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.
