Jetty scenario with logging turned off, obviously, involves practically no I/O at JRuby level at all. I've tried to profile it, and saw no obvious bottlenecks in core classes. Most of the CPU time seems to consumed within the JRuby runtime stuff (ThreadContext, RubyObject and such). By the way, Petstore is a very simple Rails application. I'm going to do some comparisons with a couple of much bigger apps TW is building, we'll see how that stacks up. I won't be able to publish it, like Petstore, but I'll try to at least write up the general observations. -- Alexey Verkhovsky CruiseControl.rb [http://cruisecontrolrb.thoughtworks.com] RubyWorks [http://rubyworks.thoughtworks.com] --------------------------------------------------------------------- To unsubscribe from this list please visit: http://xircles.codehaus.org/manage_email
