Hi Robin,
we have the same performance issues with 25.10.4 running on DEC3862 Hardware. Using Inter-Vlan Routing, we can't get more than 1.40 GBit/s.
We were wondering why our backups couldn't be finished. We had a time schedule in the policy for this Traffic
We are using Zenarmor. Adding the destination device to the exempt list will gain 200Mbit/s. So 1.60 Gbit/s through the firewall connected via 10G.
Here are some Log-Entries regarding netmap-driver:
