Should I stay in UFS

[mapsware]

Hi, my main concern is memory

Should I install 23.1 to enable ZFS or only upgrade and stay in UFS

This are the specs of the equipment

Versions = OPNsense 22.7.11_1-amd64
CPU type = Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz (2 cores, 2 threads)
real memory  = 1074790400 (1025 MB)
avail memory = 991195136 (945 MB)

With 1G of memory stay with UFS.

I think you should consider upgrading your hardware at least to meet current hardware requirements (eg. 2GB RAM). Your platform most likely uses DDR3 memory which can be obtained extremely cheap nowadays (eg. less than espresso in semi-decent cafe per gigabyte).

If you can't upgrade then stay on UFS, if you can then get at least 4GB (this should be enough for single 128GB SSD) and migrate to ZFS.
