Given that the CRS125 units are using an Atheros AR9344 600 MHz CPU I would suspect that routing performance will be slow, which is understandable. I am more concerned about overall maximum throughput. Is there a block diagram available for this unit yet? What kind of performance should I expect from using link aggregation? If it’s like some of the RB units with one 1Gb internal switch then link aggregation will not be a benefit at all.
UPDATE: Normis responded to me in this thread with a block diagram: http://forum.mikrotik.com/viewtopic.php?p=394035#p394035
