it shouldn't be, that rule was based around systems in the days when a stick of ram cost half a months salary... forget it. if you have the ram you won't need the swap... alwasy a good idea to have some anyway... a coupla hundred megs can't hurt...
In short - it doesn't need to be. It was a sort of unwritten rule that people followed as a guide when creating swap partitions. If you have plenty of ram 1GB+ then you prbably don't need 2GB swap. Swap files are useful though when working with large amounts of data though - like large graphics etc. There was a similar thread not that long ago. http://www.linuxquestions.org/questi...658#post275658
Here are the 2 things I wresle with when deciding how much swap to use.
1. If you don't have enough swap your programs or operating system could freeze or crash.
2. If you have too much swap, you waste disk space.
I have heard the 2 times rule (4 times on really low RAM), 2 times up to 256MB (then equal or half, down to 256), and that people doing heavy compiling use 1GB or more.
Consider, how much RAM you have, how much do your programs and OS require.
Say you have 256MB RAM and a 40GB hard drive.
What's the difference between using 256 or 512? Not much.
I heard that for linux gui is not built in?
Even though I donot exactly know what it means, i think it implies i may have the freedom to select GUIs. if so, what are those available options, and how much memory do they need( is swap necessary)?

Originally posted by wr3ck3d gnute, are you serious?? yes, swap is just extra incase the ram fills up. but it really doesnt get touched. So if you have 5 gigs swap, thats about 4.75 gigs wasted to nothing.
I open over 20 Browser Windows, And A Whole Lot Of Software, You DON'T KNOW How Much I Use PCs, so you can see for yourself why i need so much swap.
