> Reduce memory utilization of Tapestry page instances

>                 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
>
> 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.
