2.4.5 Update doubled RAM usage

[provels]

I don't use ZFS, but I built 2.4.4_3 and 2.4.5 VM's side by side, restored my config and let them go. 2.4.4_3 to the left and 2.4.5 to the right. The break in the second graph is where I was doing the initial config of the 2.4.5. On the 2.4.5 machine, I initially configured with a single core. All the chatter in the middle is where the packages were being reinstalled. I let it run until (I think) all the packages were reinstalled (I never got the final message) and then shut it down and added another core. I knew from my previous 2.4.4>2.4.5 upgrade that more memory would be required, so the memory had been increased from 1.5 to 2.0GB (home install, no big deal). Very stable on 2.4.5 since, packages in my sig. Charts from Zabbix.

I have the same memory problem after updating from 2.4.4_p3 to 2.4.5 (installed on ESXi, pfsense with zfs, installed addons: Cron, Open-VM-Tools, openvpn-client-export).
Memory consumption since last November around 512 MB, before the update it was exactly 585MB, after the update it is now 1.28GB.

I see, many people are complaining about issues like high memory usage, high ping time and etc. after upgrading to 2.4.5. That is why, I still don't upgrade my pfsense to 2.4.5.
Hope pfsense team to see the all issues on 2.4.5 release mentioned on this forum and fix them in the next release, maybe 2.4.5-p1.

Memory only fluctuates when I'm changing my setup : add or remove packages.
Notably : add or remove feeds used by pfBlockerNG-devel.

The difference between pre 2.4.5 (2.4.4-RC's) and 2.4.5 : close to none.

The Post Starter means comparison 2.4.4_p3 versus 2.4.5!

In my case here the difference is not so significant: 2.4.4_p3 mem ~ 40% 2.4.5 mem ~ 50%.
Installation environment - see my signature.

PS. Running pfBlockerNG_devel and snort.

Included in my graphs ^^
2.4.4-p3 started somewhere end may 2019.
2.4.4-p2 before that.

Thanks for clarification!

I only see the increased RAM usage after updating from 2.4.5 to 2.4.5-RELEASE-p1.
As far as I can tell it's ZFS that is using way more memory. I compared similar firewalls (exact same configuration) still running the older version, and they have half the RAM usage. It looks like the big difference is in in ZFS memory usage:

2.4.5-RELEASE-p1:

Mem: 132M Active, 97M Inact, 587M Wired, 232K Buf, 122M Free
ARC: 316M Total, 86M MFU, 218M MRU, 33K Anon, 2006K Header, 10M Other
     271M Compressed, 533M Uncompressed, 1.97:1 Ratio

2.4.5-RELEASE

Mem: 67M Active, 188M Inact, 343M Wired, 180K Buf, 348M Free
ARC: 105M Total, 23M MFU, 78M MRU, 473K Anon, 591K Header, 2234K Other
     73M Compressed, 175M Uncompressed, 2.41:1 Ratio

Memory usage after the upgrade (and reboot) to 2.4.5-RELEASE-p1:
