PRELOAD your network
To preload your network, simply restart your computer (recommended, not required) and OPEN up your network once then close it. There, you have done it. Told ya, it's that simple.
Why the hell did you have to do that? Well, by loading it up once, the subsequent loading of the same network (before restart/shut down) will be improve its loading speed anywhere from 200%~500% :D
Yeah, I don't know how and why that works but past experience has told me that is the result. Probably magic anyway. Make sure you preload your stuff before presentations!!!
