SpeedFusion aggregate 2x Gbps WAN connections

Hi All,
I have a requirement to establish a 2 Gbps connection/pipe between two sites.
Between the two sites we have 2x point-to-point links, each link is running at 1 Gbps download and 1 Gbps Upload speeds.
I was wondering: How will the BPL-2500 configured with SF perform in this case?
Will we have a steady 2x Gbps pipe between the two sites? Has anyone tested performance of similar setup?
I appreciate your feedback!
