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.

Hey Racist and INcompetent FBI Bustards, where is the ANTHRAX Mailer ?
Where are the 4 blackboxes ? Where are the Pentagon Videos ? Why did
you release the 5 dancing Israelis compromising the whole 911
investigation ? If the Dubai Police can catch Mossad Murderers and put
the videos and Iranian Police can why cant you put the Pentagon
Videos ? If Iran police can put the AMERICAN TERRORIST, Riggi and
puting on INTERNATIONAL MEDIA a day after catching him without
TORTURE, why cant you put the INNOCENT patsies on the MEDIA. Why did
you have to LIE about Dr Afiya Siddiqui and torture that Innocent
little mother of 3 and smashing the skull of her one child ?

There are CRIMINAL cases against CIA CRIMINAL Bustards in Italian
courts.

FBI bustards paid a penalty of $5.8 million to Steven Hatfill, but
only because he was a white. They got away with MURDER of thousands of
Non-whites in all parts of the world.

Sorry, I dont have access to the journal papers ... or I would do
research myself.

From: fortunatus on
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.
From: fortunatus on
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.

Is that why I had to use assembly code instead of C for some parts of my
previous projects?

There was even one example where the C compiler made spectacularly bad
code. I only needed 6 pointer registers (the arch has 8), but the
compiler decided to use only one or two and spilled and reloaded them
from the stack for each use. Yay!
