It’s considered «bad» in the sense that it’s slow and inefficient, and if your system constantly needs to use swap then it obviously doesn’t have enough memory.

Why is swapping needed?

Swap is used to give processes room, even when the physical RAM of the system is already used up. In a normal system configuration, when a system faces memory pressure, swap is used, and later when the memory pressure disappears and the system returns to normal operation, swap is no longer used.

Why is swap area needed?

Swap space is used when your operating system decides that it needs physical memory for active processes and the amount of available (unused) physical memory is insufficient. When this happens, inactive pages from the physical memory are then moved into the swap space, freeing up that physical memory for other uses.

How do I know my swap size?

Check swap usage size and utilization in Linux
