In general, when you are looking for bottlenecks in code, the tool you want to use is called a "profiler". it tells you which parts of your code are using the most memory and cpu. in labview it's under block diagram->tools->profile->performance and memory. once you've identified which parts are causing the slowdown, then you may be able to think of clever ways to re-code that part to be faster.
