I'm investigating some issues with failing workflows and have been looking at execution times to find long running processes. One of the longer processes is associated with Nintex.Workflow.Features.WorkflowHistoryEventReciever. The method being used, I believe, is itemAdded. Can you tell me what is happening in the itemAdded method?
My hunch is that it is just writing an item to the list. The size of the list is not an issue since its a new site and there's less than a 100 entries.
