I am afraid I don't have a copy of InDesign, so I cannot test your specific situation. However, it would be interesting to know what part of your script is slow. Specifically, I would be interested in seeing some benchmarking to indicate whether your script is wasting more time on the "load_bridge_support_file" line or the "SBApplication.applicationWithURL" line. (I suppose calls through to InDesign could be the bottle neck as well, but that would be rather unexpected I should think.)
You can probably start off with Ruby's Benchmark library (with some decent documentation here: http://rubydoc.info/stdlib/benchmark/frames , though honestly you only really need "Benchmark.measure"). From there it might be interesting to look at other profiling results, but best to start simple.
