The script is poorly optimized. While using it, every ten seconds (apparently when it is polling the sector) the whole game pauses for a split second, I drop all frames during that moment, and it creates a constantly recurring stutter in the game that is extremely unpleasant.
In a previous post I had assumed it was a graphical glitch since it was so pronounced, but I eventually tracked it down to that module by removing and replacing them all until the pauses went away.
I don't know if anyone reads this or cares that I narrowed the issue down to that module, but if you're looking for a reason for the dropped frames and performance loss every ten seconds, that would be it.
