The following numbers have been measured with the bench package The following numbers have been measured with the bench package provided

- Simple port is the original jsmin.py port by Baruch Even **Simple port**
- jsmin 2.0.9 is a speed-refactored python port by Dave St.Germain The original jsmin.py port by Baruch Even

reason)
- slimit 0.8.1 is a minifier based on a parse/generate-iteration. Its
Python3 support seems to be incomplete. It fails with several inputs.
- slimit 0.8.1 (mangle) is slimit 0.8.1 with name mangeling enabled
- |rjsmin| is this very project
- _\ |rjsmin| is the C reimplementation of |rjsmin|
Note that jsmin 2.0.9 and slimit produce output different from **jsmin 2.0.9**

if available (it's faster then) or io (for python 3). spikes in lower Python 3 versions (especially for the big file
[apiviewer.js]).
**slimit 0.8.1**
A minifier based on a parse/generate-iteration. Its Python3 support
seems to be incomplete as it fails with several inputs. Python2
support actually starts with Python 2.6 (name mangeling uses Python
2.6 features)
It could not be installed with Python 3.0 and Python 2.4.
**slimit 0.8.1 (mangle)**
Same as slimit 0.8.1, but with name mangeling enabled.

python 3).
