Best wishes for the new year, may it be safe and outdoors again!
For a Cisco 2951 I have a speed issue. The chassis should be able to put 1Gbs through and it does so on the G0/0-G0/2 ports. However teh WIC cards do not go over 250+Mb.. And i cannot figure out why?!
Are there differend WIC manufactures? Like SIERRA for 4G? Or is it another configuration I am missing. On the G0/2 I have 800Mbs and on the G0/0/0 no more then 250+.
Does anyone know what I'm missing? Is it a Layer2 thing? Any advice would be most welcome!

No, the 75 Mbps (duplex) is what the router can support, with most of its features active, using an IMIX traffic mix, and not exceeding an average of 75% CPU. The 2951 best case performance is documented at 5.136 Gbps (aggregate). (See attachment for all the details.)
Yes, there's a difference between WIC generations; it's mainly the module's bandwidth to/from the router.
HWIC - 400 Mbps, EHWIC - 800 Mbps - vendor should be able to tell you which generation their module is.
