What kind of performance do you see if you temporarily remove the ip access-group and ip inspect commands from the interface? (Sorry if you already did this. I might have missed some posts). What's configured on the interface connected to the internal network for reference? 

What are you inspecting with ISP2-cbac? I've found http inspection has a huge performance impact on IOS platforms, limiting speed tests, sites like Youtube and anything else over port 80. Turning that off fixes a large amount of performance problems for me on the 1841 platform. I'm not sure if you're inspecting http. I usually just do tcp inspection instead. You won't even see it evident in the CPU load. The bottleneck is somewhere else but I've never been able to identify it specifically.
