I updated my "is #guile fast?" page with the new r7rs #benchmarks data and anchored Guile and #Chez in the benchmarksgame:
#Scheme benchmarks: https://www.draketo.de/software/guile-fast#other-schemes
Compared to other languages: https://www.draketo.de/software/guile-fast#other-languages
Chez is roughly factor 7 slower than C,
Guile roughly factor 18
(#Java 3.5, #SBCL 5, #Racket 12, #Ruby 60 and #Python 70)
