You may discover performance bottlenecks in your application, before or after delivery. LispWorks provides tools to help eliminate these sorts of problems. A profiler is available in LispWorks, in order to help you make critical code more efficient.
You can also tune the behavior of the garbage collector. See the LispWorks User Guide and Reference Manual for details.
There is a TTY-based debugger available to help debug applications broken by severe delivery parameters. You can deliver this debugger in the application so that you can debug it on-line if something goes wrong.
See the LispWorks User Guide and Reference Manual for more information about these facilities.
