I would say if it takes longer launching through nomachine than 
launching locally, then the problem is nomachine. This should IMHO be 
the first thing you test.

If it takes a long time launching locally the application is a steaming 
pile and you need to resolve that first.

We use thinlinc which is a similar Linux remote desktop solution 
extensively to provide a Linux desktop to our users with through 
VirtualGL 3D visualization capabilities and we do not have an issue with 
excessive launch times.
