No swap memory on PFSense Netgate SG-3100

[ioanstan]

Hi all,

My PFSense on Netgate SG-3100 shows no swap memory configured in the system (by default). Do we need to add it manually?

Zabbix monitoring server marks it as a problem.

Thank you,
ioan

You don't typically want swap on eMMC (or SSDs in general, though some are more forgiving). It would cause a lot of wear on the disk.

Why do you think you need swap? It's better to work within the limits of the available RAM in the device.

Thank you, I disabled the corresponding trigger in Zabbix.

I read that same reasoning would apply, in general, to computers with SSD. Better have plenty of memory.
