<h3>Performance Benchmarks</h3> <h3>Performance Benchmarks</h3>
<p>Performance is quite poor, as almost no work has gone into it as of yet. <p>Performance is quite poor (for the interpreter mainly, the C compiler seems to be smart enough to make even the very inefficent generated C code fast), as almost no work has gone into it as of yet.
We are currently focusing on the FUN-GLL macros and creating a more fully-featured language on top of the core Lisp using them. We will focus more on performance with the implemenation of the functional persistant datastructures and the self-hosting rewrite, and performance will be the main focus of the RVSDG IR part of the project.

Here is the core Lisp code run / compiled by the two above tests, which you can run in your web browser. The hand-written C code is an exact translation of this into ideomatic C.
