Traffic flow capacity per second

Hello,

I have a network with 200 Mb/s of traffic, I am using traffic flow for monitoring porpuse and I have a question:
How many flows per second can send this utility?

Thanks

That will depend on the routerboard used (RAM & CPU).

I have this RB https://mikrotik.com/product/RB1100AHx2 how can estimated flows capacity that this router cand handled?

is there a equation or something like that?.

Thanks.

It likely is no problem. I added traffic flow on a CCR1009 for a network running up to 450 Mbit/s and I have seen no noticable CPU usage increase.
(of course the number of flows/second is not really proportional to the network bitrate)
