I am currently developing an application (a service in fact) that will make use of two event pipes. The first will capture new events for a PointList containing roughly 1,000 alarm tags. The second will capture tag changes/additions on the server so that new tags can be signed up to the first event pipe if needed. This is working reasonably well in our development environment but eventually it will need to cover at least 8,000 tags. Is there any recommended limit on how many objects a single event pipe should monitor?
