speed difference between Guile and Racket (and Python)

[Damien Mattei]

hello,

when comparing the (almost) same code running on Guile and Racket i find
big speed difference:
still computing some logic expression Cn minimalized in disjunctive normal
form:

C9: 35" Guile MacOS Apple silicon

C10: 37' Guile MacOS Apple silicon
             10" Guile // MacOS (8cores) Apple silicon
                4" Racket // MacOS Apple silicon

C11 : 1'17 Guile // MacOS Apple silicon
C11: 56" Guile // (6cores) Intel, Linux
11" Racket // MacOS Apple silicon
22" Python sympy no // MacOS Apple silicon

C12: 1'24" Racket // MacOS Apple silicon
1'34 Racket MacOS Apple silicon
1'10" Python sympy no // MacOS Apple silicon
9' 25" Guile // MacOS Apple silicon

C13: 17' ,20', 24'(use <8Gb of memory) Racket MacOS Apple silicon
15' 37",16' 10" Racket // MacOS Apple silicon
7'50" Python sympy no // MacOS Apple silicon

par-map:
test : succeed
computation: very slow

threads:
test: blocked
computation:partial and crash

my conclusion about // is that in Guile and Racket my // schema is not
good, i have poor gain.

The strange thing was why in Guile i had :
C10: 37' Guile MacOS Apple silicon
             10" Guile // MacOS (8cores) Apple silicon
37' in sequential code and 10" in // with only 8 core speed up: because in
// code i use vectors and in sequential code list i think.

So now the question is why is Guile slow compared to Racket? is it again
about the lists like versus vectors? or not?

compared with Python sympy (no // support) it has the same magnitude order
than Racket (// almost change nothing:16' versus 17' for C13) but twice
more speed... but Python is known to be slow ( not compiled code)...

i'm running Guile in the interpreter (same for Racket), would it be more
fast in command line execution? sorry if my question is stupid, i know
Bigloo can compile rather being in interpreter,but do not know about guile
, each time i modify my code it seems to be compiled... (message: ;;;
compiling......)

last version of code is here:
