2. RTT Columns – The next three columns display the round trip time (RTT) for your packet to reach that point and return to your computer. ...
3. Domain/IP column – The last column has the IP address of the router.

Why is Traceroute so slow?

The biggest slow down with most traces is DNS resolution (assuming that you're not running over any slow links). It tries until timeout to resolve the address for each hop in the route. To test if this is the case in your situation you can do tracert -d [ipaddress]. That will force it not to resolve hostnames.
