Thanks to everyone for their very helpful advice, especially Craig, Mike and Trent. I've done a few test runs on a few small subdirectories, and the bottleneck seems to be the USB 2.0 interface of my computer, with plenty of RAM, CPU and network capacity to spare.

USB 2 is notoriously slow in this scenario. For details, look up Sarah Sharp's talk at LCA several years ago on USB 3, which solves the problems. As I recall, it isn't the actual data transfer rate that causes the poor performance, but I can't remember the details now.
