Rainbows! is an HTTP server for sleepy Rack applications. It is based on Unicorn, but designed to handle applications that expect long request/response times and/or slow clients. For Rack applications not heavily bound by slow external network dependencies, consider Unicorn instead as it simpler and easier to debug. * http://rainbows.rubyforge.org/ * rainbows-talk@rubyforge.org * git://git.bogomips.org/rainbows.git Changes: keepalive_timeout (default: 2 seconds) is now supported to disconnect idle connections. Several new concurrency models added include: NeverBlock, FiberSpawn and FiberPool; all of which have only been lightly tested. RevThreadSpawn loses streaming input support to become simpler and faster for the general cases. AppPool middleware is now compatible with all Fiber-based models including Revactor and NeverBlock. A new document gives a summary of all the options we give you: http://rainbows.rubyforge.org/Summary.html If you're using any of the Rev-based concurrency models, the latest iobuffer (0.1.3) gem will improve performance. Also, RevThreadSpawn should become usable under MRI 1.8 with the next release of Rev (0.3.2). -- Eric Wong
