--------------------------------
Hi Stack, I mean the perf has no improvement, the number of object instances
can be controlled(but Netty will introduce extra Handle instance), maybe the
Recycler is more suitable for large size Objects. And BucketEntry might be
better managed by ourselves.
> Use Netty’s Recycler to manage RefCnt and BucketEntry creation

> After dump the heap, found that the number of RefCnt & BucketEntry object

> this may improve the YGC.
