CRS 317-CPU USAGE

Good evening;
We have a SW model CRS 317 which our severs connected to it.
These configurations are done for this CRS317 as bellow:
2 ports are bridge and IP address set for it and server connected to the port 1 of the router directly. But we have a problem that is decreasing of bandwidth and increasing of CPU load however we have 1000 Mbps bandwidth on the router. Is there any solution for this problem?

Hi

Would you mind listing your config verbose?

But notice that in pure switching it should do 100gbps, but in bridging much less.
