Martin Grigorov commented on WICKET-5805:
-----------------------------------------

It is not solved directly.
But the API is enhanced and it is possible to replace the IPageStore with async 
one.
Also it is possible to replace the ISerializer with one based on 
FastSerialization, see 
https://github.com/wicketstuff/core/tree/master/jdk-1.7-parent/serializer-fast, 
or with Kryo (but this requires more configuration).

> Non blocking page serialization (fixme: session leak)

> We have a performance issue with our Wicket 1.4 app, page serialization 
> causes inconvenience to user because RequestCycle.detach() blocks the request 
> until session.requestDetached() has been handled.
> We attempted to solve this issue by invoking session.requestDetached in a 
> separate thread and thus allowing user to receive their request without 
> waiting for page serialization in SecondLevelCachePageMap. The disk writing 
> is already parallel, but serialization is blocking.
> What would be the best way to implement this? I have attached our (proposed) 
> patches.
