I accepted the default partitioning scheme for OpenSuse 13.1 on my Crucial 120GB SSD...

/swap 2GB
/ 20GB
/home 80GB

I have 8GB of memory so I have no idea why it only assigned 2GB of swap, I thought it have to be double the amount of RAM. Also, would this be enough room for updates on the root partition? Only 20GB?

I was wondering if it would be better to just make one big partition for /root and a swap partition? Or should I just leave it as it is.

Thanks

Double the amount of RAM was always a rule of thumb that wasn't very useful; for any given workload, the more RAM you have, the less swap you need, which should be enough to cast doubt on that rule of thumb.

In most use cases, with 8G of RAM, 2G is probably a very reasonable amount of swap or more than is necessary, although you can probably find use cases in which it is sub-optimal (say, enormous CFD simulations, or something).

So, how much swap are you actually using?

Leave it. there will be a benefit at the next upgrade or install.

In the KInfocenter it says Free Swap %100. I also did a Top command, here's the results...

top - 07:43:59 up 22 min, 3 users, load average: 0.07, 0.40, 0.49

Also I installed all of the updates and did the command df -h, the results are ...

df -h

So, it really doesn't look as if you have anything to worry about. Not unless there is some other application or applications that you run that will eat a whole lot more ram.

I think if you whant to hypernate swap has to be the size of ram,
otherwise swap is normaly not needed in a normal desktop environment if you have 8 gig of ram, except you do something special.

check also the swappiness option, http://en.wikipedia.org/wiki/Swappiness
on sdd desktop systems I usually put them to a very very low value

Hibernation is a good point, particularly if it is a laptop. Is it a laptop?

No its a custom built PC. Here's the specs...

AMD 3.5 GHz Phenom II X4 970 Processor
Asus M5a97evo Motherboard
2 4GB Corsair Vengeance DDR3 Memory Modules
Corsair TX 750 Power Supply
2 XFX Radeon HD 6870 video cards that I want to setup as a Crossfire configuration.

I want to try to install the Elder Scrolls Skyrim using Wine. Haven't tried that yet. I also have 3 other hard drives with some data and music on them. That's why I wasn't concerned about having a big home partition on the SSD since I keep most of my stuff on the other drives.

So far its running great. I can't believe how fast it boots up.
