I'm working with quite large databases for social network analysis too - up to 50,000 nodes. My area is mapping elite political and business networks.
I would be interested to know what software you are using and how you are overcoming the problems you are facing.
I am also happy to share anything I have that may be useful to you.
The main project I have been working on is a simple program (I have provisionally called "VNA Builder") which automates the process of building VNA files (for UCINET and NetDraw) from large databases. It isn't a terribly complicated program - it basically runs SQL queries against a database, and then does a few manipulations to tidy up the data and put it in VNA file format.
I would be interested to hear about your work, particularly the technical side of extracting data from your databases so as to input it into social network software.
