#97480 — Re: ANN: Dogelog Player 1.1.4 (Generational GC)

Dogelog Player is a 100% Prolog written Prolog
interpreter. We started seeding the implementation
of a common HTTP Server library for all targets
JavaScript, Python and Java. Lets take a snapshot of
the current API and report some performance experience.

We could complete a minimal library(spin) and
demonstrate the correct UTF-8 HTTP streaming of a
text stream. We then measured the local delivery of
a hobbit.txt file of 50'000 bytes, we also run
against SWI-Prolog. We were positively surprised by
the performance of JavaScript, Java and SWI-Prolog.
Only the Python performance was a little disappointing.

Our initial testing with CPython was consistently
very disappointing, so that we switched to PyPy,
the alternative JIT-ing implementation of Python.
With running Doglog Player via PyPy it becomes
comparable in performance to the JavaScript target,
both targets now only lack by ca 50% behind the
Java target and SWI-Prolog.
