示例1: createPooledByteBufAllocator

 * are disabled for TransportClients because the ByteBufs are allocated by the event loop thread,
 * but released by the executor thread rather than the event loop thread. Those thread-local
 * caches actually delay the recycling of buffers, leading to larger memory usage.
