Do .jsxbin files run faster than .jsx ?

ExtendScript Toolkit has a File > Export as Binary command, that generates a .jsxbin file from a .jsx file. Are "binary scripts" faster, or offer any advantage besides "hiding" the source code?

It's not a "compiled" version of javascript, it's just a mangling of the source, so it should be the same speed to run. Ironically, if anything, there will be a (tiny) delay while the app un-mangles the bin into a form that can be run by the javascript interpreter.

I tested on a real Indesign app with a long to execute case (around 80s). jsxbin format is in the end around 6% slower than the counterpart in this test. Im disappointed, I was expecting some performance benefit for having done that extra step.

.jsxbin is for encrypting the javascript code so others can not easily decompile the source code.  Many commercial javascripts for photoshop use .jsxbin to protect their code.
