Lisp to LAP compiler; LAP is interpreted by a virtual machine embedded in OpenLisp; speed improved about 2x 2003 7.5 Lisp to C backend; able to compile an application with many Lisp files to a standalone executable; speed improved from 10x to 20x 2007 8.7 Changes to match ISO/IEC 13816:2007(E) revision [7] 2010 9.2
GNU Common Lisp (GCL) is the GNU Project's ANSI Common Lisp compiler, an evolutionary development of Kyoto Common Lisp. It produces native object code by first generating C code and then calling a C compiler. GCL is the implementation of choice for several large projects including the mathematical tools Maxima, AXIOM, HOL88, and ACL2.
Steel Bank Common Lisp (SBCL) is a free Common Lisp implementation that features a high-performance native compiler, Unicode support and threading.It is open source software, with a permissive license.
Research compilers are mostly not robust or complete enough to handle real, large applications. They are used mostly for fast prototyping new language features and new optimizations in research areas. Open64: A popular research compiler. Open64 merges the open source changes from the PathScale compiler mentioned.
A native code compiler named "Python" (not to be confused with the Python programming language). If Common Lisp source code has been written with appropriate declarations and is organized with speed in mind the Python compiler generates code that is almost free from overhead compared to code compiled from languages like C++.
CLISP is extremely portable, running on almost all Unix-based operating systems as well as on Microsoft Windows.Although interpreting bytecode is usually slower than running compiled native binaries, this is not always a major issue (especially in applications like Web development where I/O is the bottleneck).

Clozure CL (CCL) is a Common Lisp implementation. It implements the full ANSI Common Lisp standard with several extensions ( CLOS MOP , threads, CLOS conditions, CLOS streams, ...). It contains a command line development environment, an experimental integrated development environment (IDE) for Mac OS X using the Hemlock editor, and can also be ...
