Your CPU might not be powerful enough, or your system may not be sufficiently performance-tuned, or the MTU value is not correct for your 10 Gbps Ethernet connections (you would want to use an MTU value of 8000 or 9000). Also make sure that the two 10 Gbps Ethernet interfaces are connected correctly with the right IP addresses between the host computer and the radio.
