Ian Boston commented on SHINDIG-451:
------------------------------------
Update on the comparative tests, below,
Some observations.
1. Its not that easy to get reliable memory stats, so these might be wrong.
2. The SF JSON library is serializing all properties (as per the output)
whereas the original implementation was serializing only the properties that
have been set.
3. SF JSON takes 60% of the time and about 75% the memory overhead per pojo ->
json string conversion wrt the ORG JSON version, however the output is about
10x the size due to sending empty values.
4. I still don't have comparative results on input, but input on SF JSON is
more expensive than output.
BTW, I am seeing error bars of about +-10% on most of these figures.

> JSON Serialization using net.sf.json-lib
> ----------------------------------------
>
> Key: SHINDIG-451
> URL: https://issues.apache.org/jira/browse/SHINDIG-451
> Project: Shindig
> Issue Type: Improvement
> Components: OpenSocial feature (Javascript), RESTful API (Java)
> Reporter: Ian Boston
> Attachments: SHINDIG-451.patch
>
>
> Progress on a patch to use json-lib to perform serialization of the inbound
> and outbound json messages, at the moment it re-uses the rhino from Shindig
> 412, but only in the tests to give finer grain control in the test cases. The
> Enum handling in json-lib is neat :).
> The unit tests that are not currently working are disabled with a Xtest, but
> Person and activity with some depth in the tree are working.
> Will attache the patch in a moment.
