With Matz Ruby, XEpollThreadPool is only a win if much of your code/extensions releases the GVL (or if you don't feel like porting your code to take advantage of EM). > *EventMachine.threadpool_size = 50 > I found this code and run perfectly.

"lock slowness" - which version of Ruby is this? Did you modify your app to use app.deferred? + TryDefer as I pointed you to in the other message? > Could it be that the controllers of the rails would run without > party pool threads only with EventMachine (C10K) while others > would use the controller with EventMachine thread pool (erp)? That should allow some rails controllers to use threads (app.deferred? => true) while others do not use threads (app.deferred? => false). Keep in mind this is not a very common configuration, so not many people have experience with it in production. _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying
