Hi,
Since the devices were on the same lan segment without any vlans and there probably would've been other devices on the same L2 & L3 in between the wanop devices, I suspect the config needed to looks something like the attached.
I don't have any info on the tests other than this thread so cannot comment. If the objective was to test on the lan with a wan emulator/simulator in the middle, then as a POC it should have worked. If the objective was to increase LAN speeds e.g. 100-1GbE then it is most likely that throughput would have decreased. Often users have some other type of network issue e.g. TCP Window scaling failing and look at wanos as a patch.
That said we have test benched Wanos at 2 Gbps on a 2x Xeon E5310 appliance at about 35% utilization. The drawback on this high throughput rates is that optimization ratio's suffer and in this particular case 10% reduction on generic internet traffic and 90% on compressible data. This is something that we can reintroduce at any time.
Also on the subject of throughput, the terms Core and Edge will fall away and be replaced with Optimization level: High, Low. Perhaps its an option to re-enable the max throughput optimization and make the terms High, Medium, Low or a scale e.g. 1-5. Then this enables the designer to select the balance between optimization and throughput.
