AM62P-Q1: when AM62P works as EtherCAT master, the performance issue

Hi Semon, 

To my knowledge, there is currently no AM62P specific EtherCAT master performance data on any EtherCAT master we have worked with in the past (IBV, Codesys, Acontis, IgH). 

Cyclictest could still serve as a microbenchmark for indicating EtherCAT cycle time performance, but there is no one formula/direct mapping to convert from cyclictest performance to EtherCAT cycle time performance. https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/latest/exports/docs/devices/AM62PX/linux/RT_Linux_Performance_Guide.html

like frame processing time, throughtput, etc

Are these metrics what you are seeing customers are specifically targeting? My understanding is that cycle time is the key metric and things like throughput aren't as important in the context of EtherCAT since the amount of traffic usually isn't high.
