I believe that the original commit took approx as long as the sync, so
yes, it probably took about 1 - 1.5 hours for the commit. It was probably
on the order of 1 Gigabyte across the internet for the original commit and
I'm fairly sure it was about 1.5 hours for the svnsync back to our local
slave server from the master in Huntsville because I started watching the
network traffic between the machines while I compared the repository
versions on both machines by browsing them in my web browser.
