It is normal and can be a good thing for Linux systems to use some swap, even if there is still available RAM. This command creates a 1 gigabyte file: dd if=/dev/zero of=/swap bs=1M count=1000. Heap memory can be allocated up to the size of the biggest available free block in the processes virtual memory (VM). The total amount of memory in a Linux computer is the RAM plus swap space and is referred to as virtual memory. Click the square button to disable it. Click on System. For instance, if you have 512MB memory, you can set 256-768MB virtual memory (the total size of RAM and virtual memory is generally above 256MB). In computing, virtual memory, or virtual storage is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory".. A process known as swapping is responsible for transferring the data to a swap file when the Random Access Memory (RAM) doesn't suffice. Uncheck Automatically manage paging file size for all drives. Click Change in the Virtual memory frame. There isnt a way to directly adjust the size of the swap file. Select Custom size. With Physical Memory (RAM) amounts of 4GB to 24 GB we suggest having a page file minimum size set to 2 times the amount of Physical Memory (RAM) in the system. But, If you have between 2gb and 4gb of RAM, the size of the swap partition should be half the RAM. It writes to "swap" with 1024 bytes at a time (blocksize) 1024k (1024000) times (the count argument) until we have a file with the size 1024MB. For example, if your computer has 2 GB of RAM and you open a large number of programs or large number of files, your computer might need to store 3 GB of data in its working memory.

On the Virtual Memory box, uncheck the Automatically manage paging file size for all drives checkbox. Go to advanced, settings and performance. If RAM is > 1 GB, swap >= the square root of the RAM but < 2x RAM. In this scheme, the operating system retrieves data from secondary storage in same-size The memory module shows the virtual and swap memory information. Thus, the combination of physical memory and the swap space is the actual amount of virtual memory available. The process of converting from megabytes to gigabytes is the same for all units of memory. Under Performance, click Settings. Therefore, using a portion of the hard disk as virtual memory can decrease performance. So let's say you have 4 GB (1 GB = 1,024 MB x 4 = 4,096 MB) of memory. VMware Workstation allows you to make the following memory-related settings: The memory size of a particular virtual machine The amount of the host computer's RAM that can be used for virtual machines.
