Motivation: Remove the synchronization bottleneck and so speed up things Modifications: Introduce a ThreadLocal cache that holds mappings between classes of ChannelHandlerAdapater implementations and the result of checking if the @Sharable annotation is present. This way we only will need to do the real check one time and server the other calls via the cache. A ThreadLocal and WeakHashMap combo is used to implement the cache as this way we can minimize the conditions while still be sure we not leak class instances in containers. Result: Less conditions during adding ChannelHandlerAdapter to the ChannelPipeline |
