Scheme compiler of Guile 1.9.2

[weblily]

Compiling LilyPond's scheme code might lead to a considerable speed up. 
Guile 1.9.2 comes with a scheme compiler. I 've tried now for some time 
to get the compiler running, but it will need some more work.

* Is anyone doing the same and wants to share his/her experiences with me?
* Are there any opinions about possible speed ups? Does using a compiler 
for Scheme make sense after all?
