Swap partion

Currently running SolydX EE addition. Do I need to have a swap partition? I have 4megs of memory in my system.
Looks like it was deleted during install.

swap mainly used for standby/hibernate so if you're not using them, you don't need swap.

Thank you. I'm really enjoying Solydxk EE.
And thanks for helping me learn to use this distro.

Swap usage also varies depending upon how heavily loaded the system is.

If you try to simultaneously edit a bunch of 48 Mpixel images, some 8K video and manipulate a large in-memory database, you'll probably find that some of your application will stall or (very unlikely) that you system will crash if you don't have a reasonably sized swap area.

Back in the SysVr2/3/4 days, the rule of thumb was that the swap area should be 150% of installed memory. I don't know if that's still true (I doubt it), but you'll probably find that your system runs much smoother with an enabled swap area.

Note that it doesn't have to be a separate partition. It can just be a file.

Code: Select all

#dd if=/dev/zero of=/swapfile bs=1MiB count=$((6*1024)) && mkswap /swapfile && swapon /swapfile
will create and enable a 6GB swap area in /swapfile.

That way you won't have to modify your drive partitioning.

Good luck,
