Note that since January/2005 I have stopped updating benchmarks. Too much changes are occurring on the Debian shootout site and too quick to keep up. Old benchmarks are abandoned and new once are specified.
Actually the old abandoned benchmarks are still shown, you just need to know where to look
//http://shootout.alioth.debian.org/old/benchmark.php?test=all&lang=newlisp&sort=fullcpu
The new benchmarks have settled down, these are stable
binary-trees
harmonic
k-nucleotide
mandelbrot
n-body
nsieve-bits
pidigits
reverse-complement
spectral-norm
threads
threads-flow

Perhaps sometime in the future I will continue this. I believe the old benchmarks currently shown here: http://newlisp.org/benchmarks/ are enough to paint a picture about newLISP's performance and code comparison with the two most popular scripting languages.
