There are lots of different bottlenecks in a typical network. Changing your access link speed may or may not make a performance difference. Suppose you hacked your cable modem configuration or your DSLAM configuration, and opened your access link full throttle. Would you be able to download 27Mbps cross-country from your favorite server? It depends where the bottleneck was. All things being equal, a faster access link usually results in better performance. But I would think the people on this list would know better than most, that things are almost never equal in the network world. Remember all those debates whether Keynote or other performance tests were actually valid measurements.
