Once you get more time away from screwing Palestinians, and other false-flags, you will find ideas like these How to make Lisp go faster than C Didier Verna Abstract Contrary to popular belief, Lisp code can be very ef- cient today: it can run as fast as equivalent C code or even faster in some cases. In this paper, we explain how to tune Lisp code for performance by introducing the proper type declarations, using the appropriate data structures and compiler information. We also explain how e ciency is achieved by the compilers. These techniques are applied to simple image process- ing algorithms in order to demonstrate the announced performance on pixel access and arithmetic operations in both languages. ======= Standard Disclaimer, nothing personal http://www.youtube.com/watch?v=lX18zUp6WPY http://www.youtube.com/watch?v=XQapkVCx1HI http://www.youtube.com/watch?v=tXJ-k-iOg0M Hey Racist and INcompetent FBI Bustards, where is the ANTHRAX Mailer ?

From: fortunatus on 14 Jun 2010 13:53 For crying out loud, the best any compiler can do is make optimal machine language. Many C compilers can do that over most inputs. So can many Lisp compilers if you give the right type data. So it's a moot point. The only point to discuss would be that Scheme - in the R5 version of the spec at least - doesn't have standard way to specify type data unless I am mistaken. Therefore you will find that Scheme compilers add their own syntax for it. Again we are led to a moot point.

One point that might be interesting, you do include C++ in your post. Therefore some compare/contrast of C++ class member function invocation rate versus Lisp object method invocation rate might be meaningful. I'm sure if you Google back through comp.lang.lisp you will find plenty on it already. |
