rJSmin - Benchmark
====================
.. contents::
:local:
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 :file:`docs/BENCHMARKS` file in the source
distribution contains a more comprehensive list.
Here's the list of benchmarked implementations:
**Simple port**
The original jsmin.py port by Baruch Even
**jsmin 2.0.9**
A speed-refactored python port by Dave St.Germain. There are some
spikes in lower Python 3 versions (especially for the big file
[apiviewer.js]).
|**rjsmin**|
this very project
**_**\ |**rjsmin**|
The C reimplementation of |rjsmin|
Note that the various implementations produce output different from the
original jsmin.c for one reason or another. Also the simple port was
modified to use ``cStringIO`` if available (it's faster then) or io (for
python 3).
And here's a list of the benchmarked javascript files:
- apiviewer is a file from the qooxdoo framework. Very big and already
compressed.
- bootstrap is the popular twitter toolkit, version 2.0.4
- DateTimeShortcuts is part of the Django admin interface (1.8.5)
- jquery is jquery-1.7.1.js; the uncompressed development download.
- knockout is knockout-2.0.0.js, the compressed download.
- markermanager is the V3 port of the google maps markermanager.
Inside the parentheses are size information in KiB [#]_\. The sign
behind the size value denotes the size difference in relation to the
simple port (i.e. jsmin itself).
.. [#] Bytes / 1024 for Python 2 and Code Points / 1024 for Python 3
