Performance

This page gives an overview, of what to currently expect in terms of performance from Nuitka.

Pystone Results

The results are the top value from this kind of output, running pystone 1000 times and taking the minimal value. The idea is that the fastest run is most meaningful, and eliminates usage spikes.

Note

For the pystone benchmark, higher values are better. The numbers in parenthesis are factors, comparing to the uncompiled version.
