Mainstage loaded with kontakt libraries

Hello there,

I am using Mainstage 2 and just built a concert to play later this month.

I have 12 sets, each one with 3 to 4 patches.
There are at least one patch common to all the sets.
Is this going to go heavy on the system? This patch is loading kontakt with Morphestra and Evolve Mutations 2 on every single set.

Is there any tricks to save machine power? Ram is full and I never had any problem with mainstage before, but I have never used a concert so full of patches before, so there is the reason for my fears.

Tks,

Ricardo
