How can I make this? increasing your input queue on the GigE port

Ilir,
Looking at the stats, and mostly due to the fact that you have NAT enabled, I would say this is what the box can handle.
I would try increasing your input queue on the GigE port, as I can see quite a lot of drops there, which could be due to the NAT fixups.

Ilir,
Can you provide some more info please?
What kind of NPE processor do you use?
What is the total bps/pps rate you are running at?
If you could share a "show run" maybe we could provide more feedback.
Thanks
Arie
