How to Add swap space

[CharlesV]

I see people all the time with no swap file or swap space, and many dont understand a) that even a little swap space is VERY good for your system, and b) how to create swap once your up and installed.

The reality of the first part is that some swap space is required for some applications to properly run. Even if you have gobs of ram, the reality that some applications need 'a little swap space' , or will just check for it before they start, or will even allocate a little swap space just in case.

Many times the creation of a small swap space will resolve "odd issues" that are hard to pin down, and creation of a swap file even can help test / resolve some issues.

So, how can you easily check and create swap ? ... This is the best guide I have found and covers checking, turning on and off and creation of both types of swap.

@CharlesV Thanks for the link and article, I get these as pdf's incase I lose my own memory in future days passed.

Your very welcome! and yes, I have both links and PDF's of too :-)

ZRam and Zswap

zram (previously called compcache) can create RAM based compressed block devices. It is a module of the Linux kernel since 3.2.

If physical swap devices exist, they will also be used by the system, but with a lower priority than a Zram device.

Similar results as with Zram can be achieved with Zswap, though Zswap needs a physical swap device (or swap file).

Zswap
Zswap is a lightweight compressed cache for swap pages. It takes pages that are in the process of being swapped out and attempts to compress them into a dynamically allocated RAM-based memory pool. Older pages can be evicted to disk making this a sort of write-behind cache. zswap basically trades CPU cycles for potentially reduced swap I/O.

Alternative

Similar results as with Zswap can be achieved with Zram though eliminates the need for physical swap device.

How to Add ZRam and Zswap with antiX memory manager GUI

antiX memory manager is a Control centre script allowing for checking and managing the way the Linux kernel handles memory usage, in particular activating and deactivating memory compression by zram and zswap.


Page : https://gitlab.com/Robin-antiX/antix-memory-manager

How to install :
Click bin > antiX-memory-manager > click download button
Add extension .sh example antiX-memory-manager.sh
Make shell script executable

Code: Select all

chmod 755 antiX-memory-manager.sh

Run from terminal

Code: Select all

sudo ./antiX-memory-manager.sh

If MX is installed without specifying a swap partition , will it automatically use root partition file /swap ?
In which case we only have to ensure the root partition has enough free space (say 2x RAM size).

I always specify a root partition but for the most part it goes unused on systems with >4G RAM

If you use the 'automatic install using entire disk' option, a swap file will be created by default. If you use any of the custom install options, it is up to you to create a swap partition. or. follow these instructions to create a swap file post install:
