Hi,

I connected MPBM through RS232 to a custom board running at 400 MH/s (Kintex 325) and I'm getting 9% cancelled shares. Is that acceptable value? Does that mean that I loose 9% of my computing power?

I'm wondering if it's better to connect two such boards to two RS232 ports or design a new dual-FPGA board that shares work between two FPGAs - in the first case the canceled rate should remain the same and in the second case it should be halved. But does that matter? Or is there any other way to fix that problem?

P.
