I'm not sure what swap is. But when I run out of memory, the swap usage starts going up, and my computer is slow for a couple minutes, even after the memory usage goes down (assuming I didn't have to restart my computer).
Will increasing swap size make it easy to save and quit work when I run out of ram? Or will it still be like... uh... is my computer frozen right now? I kinda hope I don't have to restart my pc...?
I believe i currently have 2GB for swap. I think. I don't fully understand this stuff.
My own experience is that when you run out of RAM and switch to swap, there is some slight slow down.
This may vary depending on how the user sets ups swappiness.
It does not freeze or crash.
You can also periodically clear out RAM:
