LagHunter is a performance bug detection tool for widely-deployed applications. LagHunter catches performance bugs in the wild, in the context in which they most likely manifest themselves.
LagHunter monitors deployed applications to gather compact reports about their behavior, which it aggregates and analyzes on a central server. It automatically produces a list of performance issues, which it links together based on the similarity of their behavior. Each issue provides the developer with information necessary to identify and fix the cause of the corresponding performance problem.
