Multi Server vrs Single Server Multichanell

Good morning Guys.
i want to run a multi channel system for three channels (stations) . in terms of performance, which is of these is advisable.

  1. Running a Single casparcg instance with three channels configured


  1. Running three instances of casparcg with three different acmp ports. one instance per a channel. All three instances are running on the same computer.

I would go with number 1 as Caspar is not really made to be run multiple times on the same machine.
