If it's faster and smaller, it seems to me that this should be something
we should work toward integrating.
How complete is this in terms of the command line option compatibility?
I also notice that Undertow implements Servlet 3.1 but without requiring
Java SE 7. That's great, except I wonder if it's violation of the
servlet spec which would probably demand SE 7 as the minimum?
Anyone else cares to make a pitch on why we should prefer this over the
current Jetty-based one?

Interesting work indeed. I guess section 2.6.3 of
https://github.com/jbartece/undertow4jenkins/blob/master/thesis/tex/projekt.pdf?raw=true
about comparison with Jetty is the crucial thing to explore, if we are
to move off of a familiar and battle-tested container.
Runtime responsiveness is definitely of interest; it sounds like the
improvements could be on the order of a few percent, which matters. Is
the measured speedup mostly related to serving static resources, or
better general stream handling, or something else?
Startup time of the servlet container is probably negligible compared
to that of Jenkins core. You suggested that startup time might be
significant in the context of Jenkins’ hour-long integration tests,
but I doubt it is a major contributor, certainly not 50%; would be
happy to be proven wrong. (By the way replacing the bundled container
has no effect on the web container used by integration tests; this is
hardcoded to be Jetty, in JenkinsRule/HudsonTestCase. Acceptance tests
using the default “Winstone” controller run Jenkins as a JAR and so
would use the currently bundled container; these also make actual HTTP
requests heavily, whereas integration tests only occasionally do so,
and so could really be affected by the choice of container.)
2% reduction in application size would be nice, though not a prime
consideration.
