I'm trying to decide the best way to organize my data for an ArcEngine application. I am particularly interested in map display and query speed. Currently I have all of my data separated into separate file geodatabases based on theme. So I have Transportation.gdb, Utilities.gdb, etc. The data doesn't necessarily need to be organized based on themes, and I'm considering putting it all in one file geodatabase.
I will be doing my own testing, but I wanted to throw the question out to the community.
In general, is using a single file geodatabase faster than using multiple (roughly 7) smaller ones? I'm interested in any other pros/cons as well.
NOTE: the software and all data will be on the customer's local machine. No data served on the web or over a network, and the amount of data is fairly small (roughly 100,000 features).
