I know, everything starts simple, I remember last year when we used our 
sample data with 12 users and 500 books, now we have 1200 users and 
100000 books (350000 objects registered in the intid utility) in the 
production system and this is just the beginning.

The simple thing is now a complex one and performance is an issue 
everywhere.
