@wy96f is this really a feature you really would like to have?
- as we moved through this task, we realized the RegionFile is not actually
doing zero-copy. it's using a ByteBuf just like before.
I bet there's an issue within Wildfly where the execution happens twice, and
the actual move would happen on a secondary buffer or something...there's a
loop within xnio capturing packets from HTTP into Netty (Wildfly has a single
port for everything).
We had a few people working on it this week, this feature is getting lot of
attention for little benefit.
If you really think this is a nice feature to have.. perhaps you can keep
going... but as it stands I would say to keep it out!

> This is of course an issue on Wildfly integration, but it seems something on
> our recent changes is breaking replication on Wildfly.
> My biggest concern is that it seems that paging catch up is silently failing
> in our testsuite and some other issues are currently hidden.
> Wildfly has an extra layer on top of Netty:
> https://github.com/xnio/netty-xnio-transport/tree/0.1
> But the main thing here, is that it seems that are other issues within
> Artemis.
> For now I'm reverting the change from ARTEMIS-2336
> And we need more investigation to bring it back
