Howard M. Lewis Ship updated TAPESTRY-2050:
-------------------------------------------
Fix Version/s: 5.1
> Optimize page construction for repeated construction of the same page
> ---------------------------------------------------------------------
>
> Key: TAPESTRY-2050
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2050
> Project: Tapestry
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.0.7
> Reporter: Howard M. Lewis Ship
> Priority: Minor
> Fix For: 5.1
>
>
> Construction of pages is probably the largest expense for any request, as it
> involves considerable work to identify what components to instantiate, what
> bindings to create, and what template tokens to be converted into what
> ComponentPageElements.
> It should be possible to devise a "page template" that is a list of commands
> for constructing a page. The current PageLoaderProcessor would generate that
> list of commands. Creating a page instance would be a matter of executing
> the commands. This would decrease the amount of time needed to generate the
> 2nd (and later) instances of a page, and would increase the likelyhood that
> common page elements for literal text could be re-used across page instances.
> Making page instance creation less expensive would allow Tapestry to more
> aggressively cull unused page instances (i.e., shorten the active window)
> while not sacrificing the ability to handle a request surge.
