Analytics time to pull large data sets

I am working on converting the pivot tables we use in Tstats over into Analytics. I'm wondering if anyone else is having the same debilitating problems in how long it takes to load data in Analytics. Pivot tables that took a couple of minutes to load in Tstats are taking 10-20 minutes to load in Analytics.

Is there something I can do to speed up Analytics' capability to pull large data sets?
