The Celluloid::IO script measures how quickly you can make connections to the server, and the EventMachine script is measuring how many times it calls the incoming data callback. The Celluloid::IO numbers definitely still seem problematic, but you are definitely comparing apples to oranges here On Mon, Jun 11, 2012 at 6:14 PM, Tony Arcieri wrote: > Hi there, this does look like some sort of bug.

As far as I can tell the entire reactor is pausing for long = periods of time. A look a thread dump shows that it is blocking on the unde= rlying system call across both MRI and JRuby. I'm getting similarly poo= r numbers on both MRI and JRuby too, so perhaps Celluloid::IO itself is imp= licated.

Would you mind opening a ticket for it?
