How To Add Swap on Ubuntu 14.04
How To Add Swap on Ubuntu? Linux divides its physical RAM (random access memory) into chucks of memory called pages. Swapping is the process whereby a page of memory is copied to the preconfigured space on the hard disk, called swap space, to free up that page of memory. The combined sizes of the physical memory and the swap space is the amount of virtual memory available.
Swapping is necessary for two important reasons. First, when the system requires more memory than is physically available, the kernel swaps out less used pages and gives memory to the current application (process) that needs the memory immediately. Second, a significant number of the pages used by an application during its startup phase may only be used for initialization and then never used again. The system can swap out those pages and free the memory for other applications or even for the disk cache.
Commands:
sudo swapon -s
free -m
df -h
sudo fallocate -l 1G /swapfile
ls -lh /swapfile
sudo chmod 600 /swapfile
ls -lh /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon -s
free -m
sudo nano /etc/fstab
Add text : "/swapfile none swap sw 0 0"
cat /proc/sys/vm/swappiness
sudo sysctl vm.swappiness=10
sudo nano /etc/sysctl.conf
Add: vm.swappiness=10
cat /proc/sys/vm/vfs_cache_pressure
sudo sysctl vm.vfs_cache_pressure=50
sudo nano /etc/sysctl.conf
Add: vm.vfs_cache_pressure = 50
