The current Thread Pool implementation in 6.0 lacks both performance and scalability on number of cores. The thread pool will be redesigned with performance and scalability in mind. The redesign will be made towards a 5.1-tree for inclusion in the 5.1 performance version. The first idea is to separate a listener thread that only listens to events and kicks up worker threads as events arrive. Also a more flexible approach to handling overload situations. The pool will only allow free allocation of threads until around 50% of them are used. After that it will be using a wait that increases as load increases. There will also be a Thread manager stub implemented where threads can report activity or non-activity to the central resource allocator.
