With CPU above 99%, there may be little you can do other than various hardware 
related upgrades such as more memory or more or faster processors. And 
increasing TCP/IP services priority or memory pool (by shifting from another 
pool) possibly won't help and might hurt, depending on how it affects the other 
processes that are eating up your CPU cycles.

Before doing anything, find out where the CPU cycles are going. If there are 
truly CPU-intensive processes, then the bottom line may be you're out of CPU 
resources plain and simple -- start planning an upgrade. But if you find that 
pointless index builds or other functions are going on that can be eliminated 
or corrected, then that's where your fix effort should go, not with TCP/IP 
services.
