Hello I bonding ether23,ether24 (crs) and ether11,ether12 (ccr) and max speed is ~1000M. When I run BT to CCR on two laptops speed is divided into this laptops example: ~600M and ~400M. I think it should be about 2000M globally.

CRS switch chip have single 1Gbps connection to CPU. So you cannot exceed this value by software bonding.

Ok, thanks. Is there another possibility to increase throughput in this case?
