New install, default setting, poor performance

[azumafuji]

I'm trying to setup a new network with OPNsense. I have a Lenovo M920q (i5-9500T), with a fenvi 2.5Gbps PCIe Network Card with 4 I226-V (rev 04) controllers.  I installed Debian 13, and I installed OPNsense in a VM using Incus.  I configured two bridge networks, one for wan and one for lan.  I attached a physical port to each bridge network: enp3s0 and enp4s0.

I have a 1Gbps fiber connection and on my current network I consistently get >900Gbps up and down. 

• When I log into the opnsense VM and test through iperf3 to lon.speedtest.clouvider.net , I'm getting >900Mbps.
• When I log into a PC on the new network connected via 1G Ethernet to the OPNsense router and I run the speedtest I get <30Mbps.
• If I test from the PC to the OPNsense router I get >900Mbps.

I've been trying the tunables, other setting that have been discussed in performance related posts and there is no change to the performance through OPNsense. I've just reinstalled so everything is back to the defaults.  What could cause such a massive slowdown going through OPNsense?  TIA!
