Transfer speed drop after some hours of uptime

[BakaPhoenix]

Hello everyone,
I noticed that my nas performance drops after a while after the boot.
For example if i trasnfer (videos) right after the nas boot i can transfer file ar around 110 MB/s which is currently the limit of my network speed since i only have 1gbps eth but after leaving it running (not doing any transfer) and transfer again videos on it speed drops to around 8 MB/s. If i reboot the nas the speed turns back to original but after sometime it stay up still drop to nothing.

Nas specs are as follow:

Intel i7 3770k
Asus Maximus V Gene
32 GB DDR3 Ram
Nvidia GeForce 1650 Super
Corsair RM 550x PSU
4x4TB RaidZ1 Pool
Single 2TB Drive for Time Machine

The main pool is shared using a Multi-protocol (NFSv3/SMB) share and i noticed the slowdown on both my Mac Mini and my Win10 PC.
Checking /var/logs/message i only get this error repeaded every 5 minutes:

The list of my kubernates apps is:

• Nextcloud (truechart)
• wg-easy (truechart)
• cloudflareddns (truechart)
• qbittorent (truechart)
• traefik (truechart)
• jellyfin (truechart)
• handbrake (forked docker image that support nvenc from here)

I'm also running a bridged interface to make my vm access the nas.

Can someone help me figure out what is the problem?
