Also I forgot to answer this-
In general I recommend against having multiple instances of Kangaroo running at the same time in one GH doc.
I don’t think it generally has a huge impact on performance, but I just can’t think of any application where there is an advantage to running separate simultaneous solvers.
If it is about getting access to different groups of points/geometry separately, you can use Entwine on the input and ExplodeTree on the outputs like this
