### Using swap
|
||
|
|
|
||
|
|
Swap can be utilised by the system to free up space in RAM. For most use cases it is recommend to create a swapfile that is one and a half times the size of your RAM.
|
||
|
|
|
||
|
|
To create a swapfile of 8 GB use:
|
||
|
|
|
||
|
|
```
|
||
|
|
# dd if=/dev/zero of=/swapfile bs=8M count=1024 status=progress
|
||
|
|
```
|
||
|
|
|
||
|
|
To create a different size of swapfile, change the `count=` amount to a desirable size.
|
||
|
|
|
||
|
|
Then to actually add the swap space to your system issue these commands:
|
||
|
|
|
||
|
|
```
|
||
|
|
# chmod 600 /swapfile
|
||
|
|
# mkswap /swapfile
|
||
|
|
# swapon /swapfile
|
||
|
|
```
|
||
|
|
|
||
|
|
To mount the swap to the system at boot, add the swapfile to your `/etc/fstab`:
|
||
|
|
|
||
|
|
```
|
||
|
|
/swapfile none swap defaults 0 0
|
||
|
|
```
|
||
|
|
|
||
|
|
And do not forget to reconfigure the kernel after updating`/etc/fstab`:
|
||
|
|
|
||
|
|
```
|
||
|
|
# xbps-reconfigure -f linux<version>
|
||
|
|
```
