Hello I have a problem:
I have one C2651XM 48F/256D with one WIC-ADSL on a 7M/512k ADSL LINE
Just a simple ACL inbound, NAT1-1 towards client and nothing else. I get at 3mbit throughput download, about 25% CPU usage.
It seem very high to me, since I plan to put later a second WIC ADSL to use a second adsl line.
(actually in the router there are 4 wic adsl, but two will be removed , and the NM-2W with them).
IOS is 12.4(25)b IPBASEK9
This is my current conf:
