At least with abcl you may want to consider using the builtin compiler for a considerable speedup, don’t know about the others:
C:\>abcl
CL-USER(1): (defun fib (x) (if (< x 2) 1 (+ (fib (- x 2)) (fib (- x 1)))))
FIB
CL-USER(2): (time (fib 39))
86.97 seconds real time
0 cons cells
102334155
CL-USER(3): (compile 'fib)
FIB
NIL
NIL
CL-USER(4): (time (fib 39))
8.958 seconds real time
0 cons cells
102334155
CL-USER(5):
I started with the infos from https://github.com/elahtrebor/RLWRAP-SBCL-LISP-COMPLETIONS and ended up with
for running my own Lisp on debian (actually Windows10/wsl/debian). If I enter
(remove
and hitTAB
three times thenrlwrap
will show meremove
andremove-if
so maybe that’ll help you.
