Wondering why my blocks are processing so slowly. Peers ranging from 0 to 10. About 45,000 blocks behind... Processing 1 block about every 5 seconds.

You are not alone. The network was under DoS attacks for several weeks. They spammed the nodes with special transactions exploiting too low gas costs for several operations.
Yesterday (Oct-19, 2016) was a hard fork to mitigate that attack by increasing gas costs for several operations. After block 2,463,000 your synchronization process will go back to normal.
