Is Lisp Slow?
Staging Area for the Common Lisp FAQAnswer 2: Some free Common Lisp implementations have native-code compilers that are about half as fast as C. This translates to 2-4 times the speed of Java and 50-80 times the speed of Perl, Python, or Ruby. Refer to http://www.norvig.com/Lisp-retro.html for details.

Frequently Asked Questions for comp.lang.lispScheme is a member of the greater family of Lisp languages, assuming that is considered to include others like Dylan and Emacs Lisp. The design of Scheme predates the ANSI Common Lisp standard, and some CL features such as lexical scoping may be considered to have been derived from Scheme. More detailed comparative discussions don't generally prove very productive; those that are interested in discussing Scheme should first consider discussing it in comp.lang.
Related QuestionsCome on, indulge us. Why do people say Lisp is slow?
Staging Area for the Common Lisp FAQSome people associate Lisp with the old hardware it used to run on (the PDP-10 was a popular platform, I hear) Lisp is interactive, which a lot of people take to mean that Lisp is (always) interpreted. Early lisps (and others, like CLisp) are interpreted, although most modern lisps are compiled.

Related QuestionsWhy doesn't Common Lisp have continuations?
Frequently Asked Questions for comp.lang.lispContinuations are a great theoretical tool; if a language has first-class, multiply invocable continuations then one can build threads, exceptions, coroutines, and the kitchen sink on top. However, there is an implementation burden with continuations; supporting first-class, multiply invocable continuations complicates things tremendously for the Lisp implementor.

Related QuestionsHow can I learn Lisp?
Lisp FAQThe way to learn any language is to write programs in it. You have two main dialects to choose between: Scheme and Common Lisp. They each have advantages and disadvantages, but the differences between them are tiny compared to the differences between them and other languages, so if you want to start learning Lisp, it doesn't matter which you choose. There are good books about both dialects, and many good free implementations.

If so, you should simply look for a Common Lisp implementation or development environment, without regard to how expressions are processed. Although native machine code Lisp compilers have been available since the early 1960s, many outsiders still tend to refer to Lisp environments as "interpreters", with an implied assumption of poor performance.

Common Lisp FAQABCL (Armed Bear Common Lisp) is an implementation of ANSI Common Lisp that runs in a Java virtual machine. It provides a runtime system, a compiler that compiles Lisp source to JVM bytecode, and an interactive REPL for program development. It runs on any platform that support Java 1.4 (or later), including Linux, Windows, and Mac OS X. It is, by the author's admission, a relatively young implementation, and has some notable limitations in its CLOS implementation.
