It's IP traffic going through the router. But there can be many reasons why
the utilization is high. Some of those are:
Access lists
NAT
a DOS occurring
a poor configuration - disabled route-cache, etc
Older IOS version which doesn't support fast switching of certain traffic
types.
Here's a pretty good doc on it:

If you want to send me a 'sh tech' - make your telnet buffer big - I'll
take a look at it.
