MAX-OTG-U4-SF SpeedFusion Max Throughput

What is the maximum throughput of MAX-OTG-U4-SF?
How about in speedfusion mode?
Just double confirming as well whether it supports both 3G/4G USB dongle.
and speedfusion peers, only 1???

Router throughput of 100Mbps.

SpeedFusion Throughput (Encryption Turned Off): 50Mbps.
SpeedFusion Throughput (AES 256-bit Encryption): 20Mbps.

2 SpeedFusion peers.

And yes both USB 4G/3G dongles.

Thanks Kurt
