Have you tried running a 'top' session from the command-line?

Most of the time, computers only use a small fraction of their CPU power. In fact, many computers use less than 5% of their CPU the majority of the time. When you open an application, play a video game, or encode media file, the CPU usage will rise or spike temporarily. Once the CPU intensive process completes, the CPU usage should once again drop down to lower level.

"System Activity" under Diagnostics will show you the Top N programs consuming CPU. Sine you're asking, it's probably Snort, Suricata, or Squid.
