This is easier to resize and manage:<\/p> # Create a 2GB swap file\nsudo fallocate -l 2G \/swapfile\n\n# Set correct permissions\nsudo chmod 600 \/swapfile\n\n# Format as swap\nsudo mkswap \/swapfile\n\n# Enable it\nsudo swapon \/swapfile\n\n# Add to fstab for persistence\necho '\/swapfile none swap sw 0 0' | sudo tee -a \/etc\/fstab\n\n# Verify\nsudo swapon --show\nfree -h<\/code><\/pre>Swap Performance Optimization<\/h2>The swappiness<\/code> parameter controls how aggressively the kernel uses swap. A value of 10 means the kernel only swaps when RAM is over 90% full \u2014 ideal for VPS environments:<\/p># Check current value\ncat \/proc\/sys\/vm\/swappiness\n\n# Set to 10 (only swap when necessary)\nsudo sysctl vm.swappiness=10\n\n# Make permanent\necho 'vm.swappiness=10' | sudo tee -a \/etc\/sysctl.conf<\/code><\/pre>
