rCSSmin - Benchmark¶
The following numbers have been measured with the bench package provided
in the source distribution. Since the numbers don’t vary much between
python minor releases (e.g. 3.3 vs 3.4), only one benchmark per major
version is given below. The docs/BENCHMARKS file in the source
distribution contains a more comprehensive list.
Said that - there is a considerable speed up of the python-only ports to
be observed with Python 3.11. Thatswhy the benchmark will list all
Python 3 versions up to 3.10.
Here’s the list of benchmarked implementations:
- YUI Port
YUI port by Zachary Voase
- rCSSmin
this very project
- _rCSSmin
The C reimplementation of rCSSmin
And here’s a list of the benchmarked CSS files:
wikipedia.css / wikipedia.min.css
bootstrap.css / bootstrap.min.css (3.4.1)
Inside the parentheses are size information in KiB [1]. The sign behind the size value denotes the size difference in relation to the YUI port (i.e. cssmin).
