Rock5B swapfile

With my Debian Radxa OS I remark that no swapfile is on. Is it necessary to add that on OS?

Sorry for may english i’m a french-canadian.

Many thanks.

IE Debian in eMMC.

这需要看你运行的程序需要多大的RAM空间.
so that

I recommend zram.
Nevertheless, you can always fallocate a swapfile, mkswap and swapon it.
