What is a RBS file ?

They are encrypted .rb files.

is it possible for a ruby cobe to be compiled ? ( in future ... SU8 ... SU9 ... etc ) i mean will a compiler be available for tis language ... or SU will be slow forever ?

There is the possibility to write a Ruby C Extension. I did that for Vertex Tools in order to get the speed I needed to crunch numbers.

This would be a Ruby feature, not SketchUp feature.

Encrypting a .rb file into a .rbs won't make a noticeable speed increase - it is simply away of protecting your algorithms etc.
If you want a significant speed increase you need to go to the SDK and that means C++ etc...
