Today the news I was waiting for is arrived... I will be to the WPC 2004 in Milan in November! 
Special thanks to my boss for the opportunity given (with sincerity, to be there by myself was too much expensive! 
).
5 interesting days are waiting me, and I'm really happy to have the opportunity to meet some friends... C U there...
In these days I'm working on a personal project with DotNetNuke and I can see that sometimes DNN (2.1.2) is slow at startup, expecially if you have lots of modules loaded.
I've personally tested that the startup performance can be increased by going to the Site Configuration settings and disable the Logging feature (by setting Logging to "0" in Site Settings or Host Settings)... obviously, this could be done if you don't need a logging feature (and I don't need it).
But... are there other way to increase performances on DotNetNuke startup? Ideas?
