when i was installing i hadnt cleaned out my second hdd that i was gonna use for swap so i skipped making one upon installation and now im wondering if i should even make one, will it improve performance even tho i have 8 gb of ram?

Oh, that's just too much ram too spare. try running conky. when you see your ram % reach 80% then you truely need one (which is unlikely)
I have only 4 Gb Ram but my swap is always 0
Perhaps some heavy task like 3D designing could use up your ram though.

You need swap if you want to suspend to ram aka put computer to sleep
Check the corresponding wiki:

ok then its quite unnecessery to add one since i dont use suspend to ram/ sleep and obviously wont run out of ram usage i guess

Not necessarily, you could always suspend to a file without having a swap partition.
EDIT: I just noticed you mentioned 'to ram'. You don't need a swap for that, you need it for suspending to disk.

You are right, I meant disk. I think if one wants to use suspending suspend2disk is a better solution since no electricity is consumed and booting is a lot faster.

My experience has been that it isn't exactly faster; it really tends to be close to the same boot time, just with a couple of apps open already once the desktop is up and running. In my opinion, that leaves me with booting clean as the better option, since it ensures proper loading of any new updates. I often need to wait for wicd to connect after resuming too, whereas on a cold boot-up it's initialized with the other daemons. This could just be my machine though; in my case, I've never shot past two-thirds my ram on a heavy workload (browser, music player, LibreOffice, XP in a VM) with 4 gigs to work with, so I don't use swap.

I have always created a swap of 512 MB -- my old machine only had 256MB RAM. That practice also made me put a 512 MB RAM in my new machine with 4GB of RAM which doesn't get used much. And obviously I don't suspend.
Maybe I should remove the swap and use the 512 MB in my home or something -- just for the heck of it.
There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

I thought that linux uses all the available memory and even more for caching. I have 4 gigs of ram and use cca 150 mb (I just have dwm, no DE) but after a day of working it can get up to 3.7 gigs.
