Please note the following is my simplistic understanding/translation from Developer (Smart guy) to SE (Not so smart me)...

Active/Active mode is not designed to get you better network throughput, it is designed to gain performance in a (FW's) CPU intensive environment.

With a 1 Gbps connection, you will not see better than a 1 Gbps (less overhead, etc) even in multicast mode (as all packets go to all members). Multicast is a little more effecent from a failover & packet processing standpoint than unicast but that's it.

If you want higher bandwidth, then you need higher speed links. If you do increase your link speed, say with 10Gps interfaces, remember to also increase the speed of the sync network, or at least tweak the sync delay and the like or you will saturate the sync network (This leading to the "Why am I only getting 12% of my bandwidth when using HTTP!?!? questions).
