If you have a swap while your system does not need it, the answer is simply no: because it will not be used anyway. If your system has the need to use the swap despite 32GB RAM, it will occupy NVMe bandwidth to the extent the swap is in use. In short, if your system does not need it, it won't affect performance.
If a system runs out of physical RAM and doesn't have enough swap space available, it may increase the likelihood of a system crash due to a memory exhaustion issue. Having sufficient swap space can prevent some memory-related crashes.
Here is the reason why disabling swap is a bad idea: If you start a program that uses up all the available memory, what pages get pushed out of the memory? Without swap, you cannot push out the dirty pages, so you're stuck with pushing out the clean pages. The clean pages are mostly the pages with the program code.
If you don't need hibernation: If there is less than 1GB of RAM, the swap size should be at least the amount of RAM and, at most, double the amount of RAM. If there is more than 1GB of RAM, the swap size should be at least the square root of the RAM amount and, at most, double the RAM amount.
If you want to hibernate your system you need a swap partition equal or larger than your physical RAM size; otherwise there's again little to no rules; consider the largest virtual memory size you may ever want -- taking into account that swapping in/out more than a few gigabytes makes for unworkably slow desktop ...
What is Swap Memory? | How Much Swap Should You Use in Linux?
Do I need swap if I have 16GB RAM?
You only need swap if you want to use hibernate for the rest it is a wast of space on your harddrive. If you use hibernation your swap should have at least the same amount as your physical ram.
As for 32GB of RAM, it can be considered overkill for gaming alone. However, if you are also running other resource-intensive programs alongside your games, such as streaming or video editing software, having that much RAM can help ensure that your computer can handle the workload without slowing down.
In short, if your system does not need it, it won't affect performance. But if your system needs it, the negative performance impact of not having swap available would be worse than the impact of the occupied NVMe bandwidth of available swap.
Having an overly-large swap partition on Linux will not cause any performance problems. Swap is used as necessary and can be somewhat controlled by swappiness. The amount of swap space allocated is never considered in the algorithms for swapping (or paging) out processes.
One common way to increase swap space in Linux is by creating a swap file. Chiefly, a swap file is a regular file in the file system that serves as additional virtual memory.
Swap memory is optional, but it is beneficial in many cases. It improves the system's performance by allowing the operating system to run programs that require more memory than is physically available. It also helps prevent the system from crashing if it runs out of RAM.
Any extra use of an SSD reduces its life. There are limits to how many times an SSD can be overwritten. With that being said, swap memory only uses a small portion of your SSD, so most of it will be perfectly safe.
To clear the swap memory on your system, you simply need to cycle off the swap. This moves all data from swap memory back into RAM. It also means that you need to be sure you have the RAM to support this operation. An easy way to do this is to run 'free -m' to see what is being used in swap and in RAM.
An option on a swap is called a swaption. These provide one party with the right but not the obligation at a future time to enter into a swap. A variance swap is an over-the-counter instrument that allows investors to trade future realized (or historical) volatility against current implied volatility.
The objective of a swap is to change one scheme of payments into another one of a different nature, which is more suitable to the needs or objectives of the parties, who could be retail clients, investors, or large companies.
Having high swap usage is not in itself an issue, but if swap usage is consistently high, you might have memory issues. You can address them by adding more memory, running fewer processes, creating or adjusting swap file use, or checking for bugs that affect OS memory.
Disadvantages. If there is low main memory resource and user is executing too many processes and suddenly the power of system goes off there might be a scenario where data get erase of the processes which are took parts in swapping.
swap space is used when you open many program and run out of RAM. If you have lot of RAM, then swap space is not really needed. Even if you create, it won't get used. It is better create swap space so in case you run out of RAM for any reason, programs won't get killed.
It tends to become higher if you have a lot of apps or tabs open at once or are trying to manage other complex processes. However, swap used doesn't always mean something is wrong. It's an indicator of potential issues, but some swap memory usage is not uncommon.
On the other hand, missing a swap area (or a large enough one) will make applications crash randomly. Additionally, depending on OS settings, the OOM killer might also decide to kill the most memory hungry applications if there is a strong RAM demand without even giving them a chance to save their (your) critical data.
If you don't have enough memory and no swap space, this will often cause failure to allocate memory for requests needing more memory pages. As a last resort, the Kernel will deploy OOM killer to nuke high-memory processes (usually MySQL, java, etc.).
1024 GB or 1 TB of RAM is definitely overkill for the vast majority of uses. There are certainly contexts where it's useful (large in-memory databases for example) but for most people it would just be a big waste of money.
DDR5 offers at least a 50% increase in bandwidth over DDR4, which has a minimum data transfer speed of 4.8 Gb/s. DDR5 needs much less power than DDR4. This also means DDR5 produces less heat, with a predictable impact on server performance.
16GB: Excellent for Windows and MacOS systems and also good for gaming, especially if it is fast RAM, though some games still need more. 32GB: This is the sweet spot for professionals and high-end gamers. It's enough to play any game, but pricing is still affordable.
