I followed your suggestion and installed "iperf" which appears to give me a far better overview than "netio". The result is that ~75MBit/s between both 10GbE interfaces. I also recognized some curious statistic values in the management interfaces of the switches. Possibly I've been searching the wrong place up to now. I will get back with further results. CU, Daniel.
