How much can a RB750 handle

Hi Guys

I am having a strange problem

Here is my setup

CCR → Rockets <— RB750 v6.1 ( in switch mode now .. also have tried bridge ) → ISP’s Cisco Router
The link running @ 50Mbps without any issues. Latency is around 2 to 4ms
When Link runs @ 61Mbps with under 20ms .. The link never completely drops, it just drops to 4Mbps with 1 to 2ms and then shoots back up to 60Mbps tx 6000p/s rx 8000p/s
When the traffic drops to 4mb I can not do a bandwidth test to the RB750

Can a RB750 handle the traffic ? The CPU never goes above 10%

I needed up replacing the RB750 with a hub and the problem is solved now .

Interesting observation. The CPU load should go up if it is unable to process the traffic or maybe there are some other issues with the RB750.
