After some scalability issues with my site I decided to make the most of multiple cores and use Cluster to create many worker processes. It makes no sense to log in and poll on every worker process, so I would like to create and share a single instance of the Tradeoffer Manager between all workers. Is sharing a single instance Tradeoffer Manager the best way to do this? Are there any features of Tradeoffer Manager that would let me use multiple instances on every worker, but not waste resources logging in and polling on each one? If sharing a single instance is the best way to go, then what is a good way to be able to access it from the workers? I would rather use a callback-style interface if possible. Thanks in advance.
