Improve Algorithms for Resource Validation and Template Localization
--------------------------------------------------------------------
Key: JS2-739
URL: https://issues.apache.org/jira/browse/JS2-739
Project: Jetspeed 2
Issue Type: Improvement
Components: Decorations/Themes
Affects Versions: 2.1.1
Reporter: David Sean Taylor
Assignee: David Sean Taylor
Fix For: 2.1.1
During load testing, we discovered the Decoration valve was calling code in the
BaseDecorator that inefficiently made calls to validate resources, combined
with applying a seldom used mediatype/language/countrycode fallback algorithm.
This effort will optimize these inefficiencies with caching and optionalizing
the fallback algorithm and resource validation. The overall expense of the
existing algorithm was leading to as much as 18-24% CPU usage per request.
Additionally, there are other calls made to locating templates like from
velocity templates, where we may gain some more performance improvement.
