Topic: does each mongrel has one instance of a singleton class?
I guess it's really stupid to ask this but i just want to confirm that i understand the singleton class correctly. In my rails app I have a few singleton classes, and then i deploy my app with a cluster of 10 mongrel servers and pen as load balancing (no round robin). I notice a performance issue related to my singleton classes, so i want to ask if it's really 10 instances of each singleton class are created on my 10 mongrel or they all share ONE instance of that class. I know rails is single thread so each mongrel is running on one thread but again i just want to make sure there is nothing fishy about singleton module.
Thanks in advance
