| In terms of efficiency Lisp is generally faster than many languages, such as Python or Ruby, but, slower than, for example, C++ or Java 6 (based on the benchmarks from http://shootout.alioth.debian.org/ by the time of writing). However, CRAM runs on a robot in real-time and the robot usually has enough time to think about its future actions while performing current actions: physical execution of actions is in most cases slower than the computation. In addition, SBCL has many possibilities to improve code using the optimization declarations when really needed. | In terms of efficiency Lisp is generally faster than many languages, such as Python or Ruby, but, slower than, for example, C++ or Java 6 (based on the benchmarks from http://shootout.alioth.debian.org/ by the time of writing). However, CRAM runs on a robot in real-time and the robot usually has enough time to think about its future actions while performing current actions: physical execution of actions is in most cases slower than the computation, so efficiency is not a major concern in CRAM. In addition, SBCL has many possibilities to improve code using the optimization declarations when really needed. |
