> Deltaspike ProxyFactory start is slow. YourKit shows that the bottleneck is in the method "collectAllMethods". It intensively uses Class.getMethod(name, args), that is known by having poor performance. It seems, that number of calls could be distinctly decreased by skipping checks of public abstracts from proxy base class. In my case it improves OWB boot time by 7%.
