Subj.
Is the difference only in using ROS in control plane of CRS? Or it may be in switching performance or available L2 functions?
Why is there no performance test results tab in CSS326-24G-2S+RM?
Is CSS326-24G-2S+RM or CRS326-24G-2S+RM sutible for connecting many servers which can have high port utilization?

Thanks in advance for clarifying this.

The only difference between CSS326-24G-2S+RM and CRS326-24G-2S+RM is RouterOS possibility, hardware is identical.
CSS326-24G-2S+RM can do switching at wire speed, I think performance table are not necessary. I`m sure both devices can deal with high port utilization and many servers.

CRS series can run RouterOS, sometimes they can also run SwOS (you can choose either).
CSS series can only run SwOS.
