---------------------------------------
Assignee: Andrea Del Bene
> Avoid serialization of untouched page after ajax request
> --------------------------------------------------------
>
> Key: WICKET-5933
> URL: https://issues.apache.org/jira/browse/WICKET-5933
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 6.19.0
> Reporter: Fridolin Jackstadt
> Assignee: Andrea Del Bene
> Attachments: wicket-5933.patch, wicket-touch.zip
>
>
> We run into a disc and cpu bottleneck on a wicket page with 10000+ users,
> that uses ajax updates via polling (AjaxSelfUpdatingTimerBehavior).
> The result of our investigation is that page store needs about 10ms for
> serialization, while the framework serializes the same data again and again.
> Our application doesn't touch the page, but the AbstractPageManager does:
> {noformat}
> IManageablePage page = getRequestAdapter().getPage(id);
> if (page != null)
> {
> getRequestAdapter().touch(page);
> }
> {noformat}
> Therefore the requested page is always touched, but we couldn't figure out
> why. If it's possbile not to touch the page here (in some cases) that would
> solve the problem.
