Thank you for those.

Results on my machine are as follows:

Guile 2.2:
================================8<================================
$ /usr/local/bin/guile --version
guile (GNU Guile) 2.2.0

$ time /usr/local/bin/guile -s performancetest.scm

$ time /usr/local/bin/guile -s performancetest.scm

================================>8================================


Guile 2.0:
================================8<================================
$ guile-2.0 --version

$ time guile-2.0 -s performancetest.scm

Apparently, 2.2 performs better, especially after compilation.
