Packet matching that statement with the "log" keyword are process switched, which will result in high CPU utilization.

Hi,
Log keyword may increase the CPU uses. If it not necessary then remove the log keyword otherwise you have to configure a rate limit on the access list. You can use following commands for the same:
ip access-list logging interval
logging rate-limit
The logging rate-limit command was introduced in IOS 12.1(3)T.

Hello,
on a side note, what platform is this on ? Post the output of 'show ver'.
Your ACL denies every IP packet, what are you trying to accomplish ? Depending on the amount of traffic, and with everything likely to be process switched, as Martin mentioned, CPU usage can spike.
