I got 12G physical memory.
I do simulations, I am pretty sure I will and I always use large memories than ordinary people, because I am running computation fluid dynamic simulation, with a large mesh always. sometime it will use physical memory up to 80% of my physical memory. But still I cannot find swap using as I have seen b4 on my 11.3. So I feel confused. Esp When I on my new 11.4 I found switching the tabs is sometime very slow than b4, like in nautilus or gnome terminal…
I use NVIDIA Quadro FX 3800 video card, I follow the step on a page of opensuse , that is “hard way”, just as I did b4 for 11.3 which worked greatly with no problem (I took notes).
Well, I don;t know how to upload a picture here on this forum. But I have already just ended up with a situation that “run up my 12 G completely, and the program crashes”, when I meshing my flow field. And even then no swap was used… Isn’t this a symbol of something going wrong…
You may or may not need swap but 2 gigs with 12 gig memory is not much use. At 80% usage with 12 gigs you still have more free memory then most desktops. Also use of swap generally does not speed anything up. It generally slows things down since it is a disk operation and is slower then RAM. It is only there to keep from crashing if you do tun out of main memory.
Did you reboot after installing NVIDIA driver? Make sure what is running, look into My Computer.

I’d do a root cause analysis on this rather than assuming it’s because
swap isn’t being used. Swap being used generally slows things down
(because it takes time to take memory and write it to disk and take
swapped info and pull it back into memory).
Start by looking in top and see what is consuming the CPU resources in
Thanks, but if you follow all the posts in this thread, you will find my point is I am confused that “even I used up all my physical memory, still swap was unused. I think this should not happen in this way, right?”
Desktop effects will wont effect swap usage but it may effect responsiveness. Ok maybe us a little less memory.
Sorry missed that post. I only see info for processor 3 I assume you have 4 CPU’s since the count starts at 0
For some reason you show no swap at all but you do have the proper mount command in fstab. I can’t remember ever seeing that before.
type as root mount all
to see if you get it to mount. Maybe you might see an error message about a problem.
It is a bit confusing dealing with 2 separate issues in the same thread.

i agree! it sounds like something is amiss in the system…
Linux will normally use a little swap even when the RAM does not
fill…but he has demonstrated he can FILL RPM and crash the system,
without using swap…
something is wrong! and i guess “swap never used” and “my system runs
quite slowly than before I worked on 11.3” are symptoms and not problems…
and, for now, despite others ideas: do NOT remove your swap partition
because it IS of use…
