No, it doesn't. And yes, it does.Does a 10G PfSense box make sense?
Netgate acknowledges that PFSense as written bottlenecks when processing at/near 10G speeds - even on advanced CPUs. There is just too much bit-copy going on in the BSD network stacks and the BSD Packet Filter (BPF, the "PF" of PFSense...). Thus their decision to develop and push TNSR for higher performance. So no, a multiple 10G PFSense that is doing a lot of bridged switch emulation between links doesn't really make a lot of sense.
However, for the application being discussed here - a lab situation, cost managed 10G, with few if any bandwidth critical applications it can do just fine. Also, for speeds between 1G and 10G it can do just fine. Much better, in fact, than link agg or ECMP across multiple 1G links. So yes, in limited cases, it does indeed make sense.
