How do you folks retrieve all objects in code upfront?

I figure you can increase performance if you bundle all the model calls together?

This makes for a bigger deal, especially if your DB cannot keep everything in memory

def hitDBSeperately {

get X users ...code

get Y users... code

get Z users... code

}

Versus:

def hitDBInSingleCall {

get X+Y+Z users

code for X code for Y...

}
