@cabrio_leo you are the Number 1 !!!!!!!!

Thanks to everyone for the answers!!!!!!.
So it's perfectly normal for the system to have this ram consumption?.
@cabrio_leo , what settings you used for the caching file ??.
Or differentiate "limits" for zfs?.

Hi macom, thank's for reply !.This is the situation of the ram used,
and it is always high even at rest.

Good evening at all , I would have a small question .
I would like to see if it is normal that my system uses 55% ram, even when it is at rest.
Lately I have noticed that using ram never returns to low values.I use the following services :
- Docker ( Sync )
- FTP.
- OpenVNP.
- SMB.
- SSH.
- Transmission ( Not everyday ).
- Zfs.
The use of so much ram can cause problems for a long time ??.Oh is completely normal, and I worry about nothing ???.
Sorry if my questions are stupid, learning is always useful.Thanks to everyone, every advice is really useful.

Hi raulfg3 thank's for reply , the tekkb's thread link is :

Example of OMV's firewall

In my case the router have upnp active , and before i put the "last rule" " reject All " the status of the port in transmission was open , also if i dont' make a rule for the transmission web port It 'doesnt work.
I take away the last rule, and restart transmission service , the state of the port on router , and in transmission web return open, so I think i have to create a rule in INPUT chain, or FORWARD chain , but at the moment I do not find the solution.

some screenshot of firewall rules in Omv tab :

Good evening every body , nobody had problem with transmission????
i post my iptables -L :

I have tried some configuration find in ubuntu\wiki iptables ,for open the port of transmission without solve the problem.
For example :
iptables -A INPUT -m state --state RELATED,ESTABLISHED -p udp --dport 51413 -j ACCEPT
iptables -A OUTPUT -p udp --sport 51413 -j ACCEPT

Every advice is well accepted

Im sorry for the double post , excuse me !!
Forgive me .

Good evening at all , i need a help for setting correctly the omv firewall rules for Transmission plugin .
I've follow the Tekkb's thread regardin 'Firewall' and when i put the last rule 'REJECT All' the port of Transmission became in closed state, and router dont recive Upnp.
My OMV3 IP is : 192.168.0.X and port for Transmission 51413 (default).
I dont understand how is the correct set for that rule, INPUT?? OUTPUT??
Any advice will be appreciate!!
Thank you all !
Please help me

Good morning at all , yesterday i was reading an article about zfs "improvement/tuning" ...I've tried some settings for the limit arc cache.
When i run the command in the terminal " cat /proc/spl/kstat/zfs/arcstats |grep c_" the result was :
c_min 33554432
c_max 8392192000
My system had 16G ram ( not so much, but not so bad ) ,so I tried to change this value creating a file zfs.conf in /etc/modprobe.d whit this parameter :

#Min: 4GB

options zfs zfs_arc_min=4000000000

#Max: 10GB

options zfs zfs_arc_max=10000000000

And then reboot the server, after another "cat /proc/spl/kstat/zfs/arcstats |grep c_" this is the new value of arc cache

c_min 4 4000000000
c_max 4 10000000000
arc_no_grow 4 0
arc_tempreserve 4 0
arc_loaned_bytes 4 0
arc_prune 4 0
arc_meta_used 4 7203712
arc_meta_limit 4 6294145536
arc_meta_max 4 7206128
arc_meta_min 4 16777216
arc_need_free 4 0
arc_sys_free 4 262254592

At moment the server run ok, and the read/write speed is higher than before, but someone could tell me if this parameter could impact on the server function ??
Someone have some advice for other improvements??
Thank's everybody

Sorry if i dont answer before , im still reading all this thead , i'm on page 15 !!
