    Performance Benchmarks

    Performance is quite poor, as almost no work has gone into it as of yet. +

    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.

    Even so, it is worth keeping a rough estimate of performance in mind. For this, we have compiled a very basic benchmark below, with more benchmark programs (sorting, etc) to be included as the language gets developed:
