For a server with low RAM, 60 could be a passable default value, but it's worth experimenting with. Change it via the command:. The default will be , but 50 is generally a good number to start with. You can type sudo sysctl vm. To make the change permanent, add the vm.

Making these adjustments will almost always help your performance in Ubuntu Just make sure you aren't too aggressive if you use an SSD or you could wear the hardware down slower. However, it's worth noting that even with these errors, with a low amount of RAM there's only so much you can do.

Tasks take far longer to complete on swap storage and you may still run into out of memory errors in some applications if you only have 1 GB. In these cases, it's best to just upgrade your server.

Jumping up a few gigabytes of RAM usually isn't that expensive and can help a lot. What is Swap Space in Linux? How to Check Swap Space in Linux It's always a good idea to check how much Ubuntu swap space if any your system has before adjusting it. You can do so with the following command: sudo swapon --show If the command returns nothing, it means you don't currently have any swap space configured. Here are some of the most commonly adjusted options and their purpose: Swappiness : How often your PC swaps data from RAM to your swap space.

A value of 0 to , denoting the percentage of available RAM you want it to swap at. Cache pressure : How often the system caches inode and dentry file system data. This often performance intensive and worth caching. The 0 to value signifies how much the system will choose to cache. To change the size of your page file, navigate to the 'System' section of the Windows Control Panel.

Open 'Advanced System Settings' and navigate to the 'Advanced' tab. Click the 'Settings' button under the 'Performance' section to open another window.

If you have a page file enabled on your machine, which you should by default, then Windows will dynamically adjust its size for you.

Initially, Windows will configure a page file size based on the amount of memory installed and free disk space available.

If you don't run memory intensive applications such as virtual machines and production software other than games, you can shrink the page file down to a fraction of your total available RAM. If you have a drive with more free space or a faster access time, you may improve performance by moving the swap file to this drive.

Windows 7 , Vista , and XP allow you to set up swap files for each drive on your system. In these versions of the Windows operating system, the swap file is dynamic and hidden.

Note: If this doesn't match what you see, refer to Get around in Windows. The name of the Windows XP swap file is pagefile. The swap file is dynamic, changing size depending on system conditions. If you run several applications at once, the swap file will grow to accommodate the additional information required to run each application smoothly.

This is a hidden file, so you will have to change your folder view setting to be able to see the file.
