      @jimp very true. Here's the monitoring page. I will keep it running and see if it stabilizes over time. Screenshot 2023-01-11 at 9.35.02 AM.png

      Thanks Jim!

        That's the CPU view, click the wrench and change it to System > Memory

              That's the processor usage, you need to select 'Memory' in the settings like:

                  Looks like a good chunk of your memory usage is ZFS ARC, which can free itself as needed if other things need the RAM.

                  The first boot post-upgrade will show high ARC/wired usage because of all the disk activity associated with the upgrade.

                  If you reboot after it'll go back down to "normal" but may grow over time.

                  But again, it's like caching RAM, any free RAM is wasted RAM.

                      Have there been changes since 23.01?
                      Does the bar contain noch wired and arc RAM as well? Or has the arc ram been raised?
                      For ~7gb ram there should not be much cache necessary.

                        ZFS ARC is counted under Wired.

                        We didn't explicitly change any tuning but there was a sizable jump between FreeBSD 12.x and FreeBSD 14.x.

                        Even on 23.01, though, some people reported the same observation where RAM usage appeared higher the first boot after an upgrade.

                        The memory in the graph marked cache is different, it's not related to ARC. But you want as much caching going on as possible to make use of the RAM rather than it just sitting there. If there is memory pressure, both cache and ARC will lower their own usage to make room for whatever needs it.

                          @jimp ok thanks for the explanation.
                          Understood and makes sense, but it is hard to see if there is ram left for eg plug-ins or not.
