rJSmin - 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 :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
