That is probably because - like said elsewhere in this thread - a new session was started for every request. > The problem is also that the CPU was on 100%. Hmm, that's interesting. We (or rather Johan and Jonathan) really worked hard at making Wicket as efficient as possible. Even with the whole object tree creation etc it should still perform very well. If you find certain hotspots, please share. > This version 2.0 sounds very nice, is it usable yet? We're also planning on backporting those features from 2.0 to our upcomming 1.3 release. All 1.2.x release are meant to be binary compatible. 1.3. will have a couple of API breaks that will make new functionality possible. When we release 1.3. it will probably be immediately usable for production as it mainly consists of back ports. You can use 2.0 - in fact we think 2.0 has a few things that makes it a lot better than 1.x, but at this time we don't guarantee API stability yet. But we plan on stabilize 2.0 in about 2 months, also because of the fact that we are writing Wicket In Action for that version. > How can I set a page to be stateless in 1.2.1 ? Is there some attribute to > do this or does it just mean that you use detachable models? Stateless means the page isn't even stored in the session. We started out implementing that automatically for pages that don't have any call backs to themselves (Links, Forms, etc). So for 1.2, if you implement all your functionality using bookmarkable pages and passing 'state' using RequestParameters objects, you'll have hardly any session usage. I say hardly here, because 1.2 still creates a session for each client. Deferred session creation was implemented for 2.0 and is on the list to be backported for 1.3. With this, you can write Wicket applications that do not even create a session for a client ever. Stateless pages for Wicket 2.0 is currently under heavy development. >From an end-user's point of view, it will support the same use case I mentioned above, and in addition to that, you can even use forms and links with stateless pages in 2.0. I lost track myself of the status of the whole stateless business in 2.0, so I started a WIKI page here: http://www.wicket-wiki.org.uk/wiki/index.php/Stateless_pages and I hope someone else (specifically Johan and Matej) can finish that page. There are several other ways to customize session usage too, btw. Most notably tweaking the number of history items that are stored in the session (IPageSettings#setMaxPageVersions), using a custom ISessionStore (the default in 1.2 just stores everything in the HttpSession object, but any other scheme is possible, including what will probably the default in 2.0: a first level that stores pages in the http session and a second level (for back button support) that stores on disk).
