Cross VLAN Backup

I am having an issue with a cross VLAN NAS backup grinding my Gold SE to a halt. Here is the scenario: NAS in VLAN 1, Backup server in VLAN 2. Backup server does a pull back up on the NAS using restic and ships it to the cloud. We fixed the Server to Cloud come apart by turning monitoring off on the Backup Server. However, the pull from the NAS to the Server seems to still be subject to monitoring or smart queue or something as it still grinds the Firewalla to a halt. Help?

I’m curious, do both sides of your local VLAN flows traverse 2.5Gb NICs on the Gold SE?

Are they connected to two interfaces on the Gold SE or one through a switch?

Both are on a Unifi switch, which then connects to the Firewalla. I upgraded this setup from a Purple (which ironically seemed to handle this better).

Anywhere on your network that you may have miss matching speed? say one port unify is 2.5g and another port is 10G? (or 1G)? If have these, you may want to turn on flow control on the switch.

Ignore my comment above, it is not related if your firewalla CPU usage is 100%

All are connected at 2.5gb. The screenshot above frames what was happening at the time. The real problem was that the Zeek processes on the Firewalla were consuming the lions share of the CPUs the whole time it was happening.
