SwapBoost for Linux

Like ReadyBoost for Vista, SwapBoost uses the extra space on a spare USB drive to speed up your OS.

SwapBoost is a surprisingly short bash script that increases your virtual memory by the amount of free space on the USB drive. SwapBoost isn’t identical to ReadyBoost since ReadyBoost does more than just turn a USB drive into swap space, however SwapBoost is surprisingly easy to get going:

1. Insert USB disk and allow gnome / KDE to auto-mount the device.
2. Run ./swapboost.sh -n to create a new swap addition
3. Check your system memory. Your swap should now be extended by the amount of free space on the device. (swapon -s will show you all available swap areas).
4. Run ./swapboost.sh -d to delete added swap and safely unmount your USB disk.

I tested SwapBoost and it worked perfectly, however, I didn’t notice any major gains in speed. If you’re having trouble getting the script going you may need to use the command chmod +x swapboost.sh to make it executable. SwapBoost is a free download, but it’s still in alpha, so proceed with caution.
