That is principally thanks to TorqBox, the codename for Torquebox 3, which is built on Undertow. Undertow is the web server that is scrapping with Netty and Vert.x on the plaintext tests.

Also note that the particular Rack test that performs very well is running a very small amount of Ruby code. Thanks to these improvements, however, rails-jruby now consistently tops rails-ruby, if only by a small amount.
