Norman Maurer 8fdf373557 Skip execution of Channel*Handler method if annotated with @Skip and just use the next handler in the pipeline. (#8723) ... Motivation: Invoking ChannelHandlers is not free and can result in some overhead when the ChannelPipeline becomes very long. This is especially true if most handlers will just forward the call to the next handler in the pipeline. When the user extends Channel*HandlerAdapter we can easily detect if can just skip the handler and invoke the next handler in the pipeline directly. This reduce the overhead of dispatch but also reduce the call-stack in many cases. Modifications: Detect if we can skip the handler when walking the pipeline. Result: Reduce overhead for long pipelines.
