It's now looking like there's something more fundamentally wrong with the system. Just tried copying 2Gb of files from my old HP (with a 100Mbit connection) to the base system with a 1Gb connection. The 1Gb connection on Mindy took longer. That shouldn't be the case. Need to spend some time with the base system doing performance profiling to confirm what I'm thinking ... that I have a fundamental configuration problem with the system.
