Just to keep everyone in the loop I thought I would send out a quick status report of where we are at: Core: A bit of time has been spent in the last week ironing out some performance problems in the core, as the core server was performing slower than both Grizzly and Jetty. Several issues were found, and most have been addressed (although not all fixes have been merged upstream yet). With these fixes we now seem to be equal to or better than both of these. On my laptop I see us being at least 10% faster than Jetty for basic servlet, and both Grizzly and Undertow max out at 140,000 requests a second when using a simple async handler, which seems to be as much as httperf can drive on my dual core laptop. A lot of the problem seems to be that we were doing to many volatile writes / CAS, so we have changed the threading model slightly so these can be removed. Servlet: I have setup a servlet TCK job on lightning (http://lightning.mw.lab.eng.bos.redhat.com/jenkins/job/tck6-as7-undertow-...). We are passing at around 85% at the moment, and these is still quite a bit of low hanging fruit, mostly in the form of un-implemented functionality. In particular, the main things that are outstanding compliance wise are Security and JSP. Security: Darren has started working on some proof of concept security handlers, and I am hoping we can flesh these out a lot more and get started on the servlet integration in the coming weeks. AS7 Integration: At the moment the AS7 integration is fairly basic, it allows for servlet apps to be deployed, and has the ability to configure the listener and the XNIO worker and that is about it. A lot of the servlet stuff piggy backs off the existing web subsystem, and uses the JBoss Metadata merged metadata to bootstrap Undertow. Because of this all the EE integration is already mostly functional, the biggest exception being web services which depends on Jboss Web internals. I don't think there is much point focussing on this just yet, until the Undertow API is a bit more locked down. Everything else: The main outstanding items at the moment as I see it are (not integration work like web services and clustering): - Https - Websockets - JSP - AJP - SPDY - Reverse Proxy Support - Transfer coding handlers - Benchmarking suite If anyone would like to work on any of these feel free to stick you hand up.
