@axing_product What happens if you take the Orbi out of the equation and plug the iMac straight into the hub in modem mode? I appreciate that the iPad was also going through the Orbi and got better results, but if the iMac isn't the bottleneck then maybe the Orbi is treating traffic from the iMac differently through some sort of QOS setting and throttling WAN speed.
The iPad results seem to me to prove that the hub is not slow in modem mode and the Samknows speed test shows that VM are delivering the correct speed to the hub.
