      This isn't the end of the world, but since I've updated to 22.01 (fresh install), the memory usage on the dashboard has been bothering me. On this ProtectLi VP2410, I've got 8GB of memory and memory usage has very slowly inched up to about 15%. Again, it's not a huge amount, but that's a bit over 1GB.

      20220221 -- pfSense Status Dashboard.png

      20220221 -- pfSense Status Monitoring Memory.png

      If I run top from the command line, I get:

      Shell Output - top
last pid: 64516;  load averages:  0.29,  0.37,  0.31  up 2+03:55:50    18:31:19
60 processes:  1 running, 59 sleeping
CPU:  0.2% user,  0.2% nice,  0.4% system,  0.0% interrupt, 99.2% idle
Mem: 87M Active, 318M Inact, 1044M Wired, 6029M Free
ARC: 323M Total, 151M MFU, 165M MRU, 33K Anon, 1271K Header, 5799K Other
     114M Compressed, 346M Uncompressed, 3.03:1 Ratio
Swap: 1024M Total, 1024M Free

      And, while I'm at it, why does 22.01 show just 3 of the 4 cores on this device for cpu utilization (see the dashboard and top)? 2.5.2 showed all 4. And, the dashboard shows the temperatures for all four.

      EDIT: I'd forget my own head .... I'm running pfBlockerNG-devel and WireGuard. During my upgrade process, I also switched to ZFS.

      I'm just a home user with pfSense 23.09-RELEASE (amd64) on a Protecli VP2410

        You mean the load average values?
        Those are not per core they are averages over 1, 5 and 15mins. It was the same in 2.5.2.

        Have a look at what's using that RAM. Using Diag > Sysetm Activity or ps -aux at the command line. Though 15% is hardly concerning really as you say.

          @stephenw10 Well, my face is red. Yep, I was looking at the load average. I had the totally wrong impression.

          ps -aux gives me (sorted by %mem and only showing non-zero values):

          That only gives me a total of 7.2% memory use, while the dashboard and top claim 15% (it's almost all Wired and looks to add up to about that number).

          Here's a similar table for System Activity:

          But, beats me how to read that.

          Again, nothing looks bad here. It just seems like a higher number than I remember. I'll keep an eye out to see if the memory utilization keeps creeping up and reaches something unreasonable.

            @areckethennu Well, the last sentence should read ... NOTHING looks bad.... But, when I try to edit it, I get a popup that some service (Akimet?) thinks it's spam.

              Fixed it. 😉

              Yeah, nothing looks unusually high there. Unbound always uses quite a bit.

                I also switched to ZFS.

                That alone will cause the system to use more RAM than it would with UFS.
