Presumably you're asking if it's a good tool to measure *available* bandwidth or lack thereof, i.e. congestion and its byproducts of packet loss and increased latency. No, it isn't! - Congestion resulting from asymmetric paths can be misinterpreted through traceroute. - Cases where ICMP performance with respect to the routers themselves is significantly lower than throughput of production traffic will often skew results. Having said that, where traceroutes suggest a POSSIBLE problem on my own network, I'd check further. However, I would never ask the operator of another network to troubleshoot solely on the basis of traceroute output.

Traceroute is a good tool for checking for routing type problems (loops). Does anyone feel it's a good tool to use for testing "bandwidth"....
