How far apart are the database and the node you are running the install from? An install/upgrade is very database intensive so you should be running from a node in the same datacenter as the database server.
Have you finished this installation? 10+ hours seems excessive for an installation. I expect that the time was being spent going across the network between where you were running the install and the database server. You want to minimize network jumps as an installation/upgrade is very database intensive.
