Tapestry page instances
[ https://issues.apache.org/jira/browse/TAP5-1508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13119722#comment-13119722 ]
Hudson commented on TAP5-1508:
------------------------------
Integrated in tapestry-trunk-freestyle #558 (See [https://builds.apache.org/job/tapestry-trunk-freestyle/558/])
TAP5-1508: Reduce memory utilization of page instances
Make template tokens directly implement RenderCommand, removing need for extra objects to fill gap
Token will be more liberally shared between page instance than the page element object (now removed)

> Key: TAP5-1508
> URL: https://issues.apache.org/jira/browse/TAP5-1508
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.3
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
> Fix For: 5.3

>
> This is an umbrella bug for a number of changes aimed at reducing the overall memory footprint of a Tapestry page. Tapestry pages have been seen to be quite large in some production sites, and the shared-instance strategy introduced in 5.2 is still insufficient. A significant amount of space is consumed using Maps and Lists (for bindings, of sub-components, etc.) in a way that is optimized for a smaller code base and efficient read access, even though most of the information is only read when a page is first loaded, and is rarely needed or accessed after that.
