This my last post about OpenLisp to not pollute tcc mailing Lisp.
Yes, OpenLisp is probably the world fastest lisp interpreter. For example,
it interprets lisp code faster than CLISP compiler.
It has 3 modes interpreter (the default), compiled to LAP with interpreted
by a VM (~ 2times faster), LAP translated and optimized in C (~20times
faster than interpreter).
Here is what you can get with standard Lisp benchmarks when compiled in C
(known as gabriel's benchmarks):
01Fib : ok, time = 0.000s. ( 0 GC)
02Tak : ok, time = 0.000s. ( 0 GC)
03Stak : ok, time = 0.002s. ( 0 GC)
04Ctak : ok, time = 0.004s. ( 0 GC)
05Takl : ok, time = 0.003s. ( 0 GC)
06Takr : ok, time = 0.001s. ( 0 GC)
07Boyer : ok, time = 0.007s. ( 2 GC)
08Browse : ok, time = 0.015s. ( 6 GC)
09Destru : ok, time = 0.001s. ( 1 GC)
10Travini : ok, time = 0.004s. ( 0 GC)
11Travrun : ok, time = 0.023s. ( 0 GC)
12Deriv : ok, time = 0.003s. ( 2 GC)
13Dderiv : ok, time = 0.003s. ( 2 GC)
14Divit : ok, time = 0.001s. ( 1 GC)
15Divrec : ok, time = 0.002s. ( 1 GC)
16FFT : ok, time = 0.008s. ( 0 GC)
17Puzzle : ok, time = 0.012s. ( 0 GC)
18Triang : ok, time = 0.079s. ( 0 GC)
19Fprint : ok, time = 0.004s. ( 0 GC)
20Fread : ok, time = 0.001s. ( 0 GC)
21Tprint : ok, time = 0.000s. ( 0 GC)
22Frpoly : ok, time = 0.023s. (12 GC)
0.194 s.
Speed can be optimized even more if compiled using profile guided
optimizations (+ ~15%)
I'll be glad to reply other questions related to OpenLisp in private emails.

OpenLisp is so fast! Interpreted code runs as fast as LAP

And LAP looks like a Half-compiled
