Using the Ruby Chatty example in my examples repo [1] I see painful slow runtime performance. To run the example, first launch the Guru process:
$ ruby guru.rb Then, in another terminal, start a single Student instance: $ ruby student What you'll see is the student starts off with a 1 or 2 messages, but then immediately gets sluggish. If you start another instance of Student things degrade very quickly. If, however, in student.rb we change: $msgr.receive(1) to: $msgr.receive(-1) then there is no apparently sluggishness until several thousand messages have been sent, and multiple instances of Student are able to run without slowing down.
