Not so much a matter of speeding things up as it is reducing the workload on the server, which speeds things up a bit but the biggest benefit is not overworking the database server so much.
So far I've made changes that resulted in the database shrinking by about 10% (which helps speed a little bit) and turned 4 of the quick database reads that were happening on every page into 2 quicker reads.
