[Ubuntu-BD] Creating a 4 GB swap partition
Hello, Recently installed opensuse but made a mistake while installation. I've installed without any swap partition. So the system is sluggish. Went to google and found out this command will create a 512 MB file and use it as a swap: dd if=/dev/zero of=/swapfile bs=1k count=524288 mkswap /swapfile sync swapon /swapfile Question is, As My ram is 2 GB I need a swap partition of at least 4 GB (It is stated on that site). What'll be the necessary changes to turn that 512 MB into 4GB file? I know it's not about ubuntu, but this command is not distro based, it's general Linux command. Can anybody help me out? -- I am me, I wanna be me.

You dont need swap partition. Leave it. 2GB is enough for a linux distro to run smoothly. I dont use swap partition for any of my linux installation. This is because all of them has enough amount of physical memory. Swap partition was used in old days, when physical memory was low.

Re: [Ubuntu-BD] Creating a 4 GB swap partition
As Shiplu mentioned, you do not really need swap if you have that much of physical memory. However, the change was needed in the count= parameter. Calculate 4GB in bytes and replace that number in count= parameter. Again, this 4GB will be a waste of memory. Also creating swapfile on the same partition does not give you much improvements. -- M.

Well at times swaps come into play. I have a habit of using more than on browsers at a time. And Firefox ate 2GB of my 2.5GB memory at one time. :) With highly resource hungry applications you might require to have more memory even if you would have a lot of Ram. But before increasing you should inspect the System Activity monitor to see if you really need a lot of swap space.
