If you're doing something more than just a simple task, it's really easy to become limited, by code size, core frequency, etc... and there's still the conception that things like LabView have a huge amount of overhead.

The LabVIEW Embedded Module for ARM is royalty free. There is no deployment license for LabVIEW Embedded Module for ARM.
Its always interesting to hear about the amount of "overhead" LabVIEW incurs. One should keep in mind that when C was first developed many engineers stated the same thing regarding overhead. Luckily as compilers improved so did engineers opinion of C. Furthermore LabVIEW is extremely optimized compared to inline C for multi-threaded muti-core programming.
When the LabVIEW Embedded code is deployed to a (supported
) ARM processor it is converted into C++ code. While this is not as efficient as programming in C the difference may eventually be unnoticeable. Isn't that the whole point of innovation?
In regards to the 2009 controller there should little performance difference between LabVIEW and C/C++.
