We have cisco Nexus9000 C9396PX 60 Gbs is data traffic, and 24Mpps ( packet per second ) not sure how to convert it into flows. Could you please share your sflow configuration if you don't mind?
I had nfsen in past with 8CPU / 4GB memory but it was damn slow :( but it could be me.. i will set up again and see if it worth it or not.
