Subject: [PATCH] Optimise non-flush packet sending
|
|
|
|
Places like entity tracking make heavy use of packet sending,
|
|
and internally netty will use some very expensive thread wakeup
|
|
calls when scheduling.
|
|
|
|
Thanks to various hacks in ProtocolLib as well as other
|
|
plugins, we cannot simply use a queue of packets to group
|
|
send on execute. We have to call execute for each packet.
|
|
|
|
Tux's suggestion here is exactly what was needed - tag
|
|
the Runnable indicating it should not make a wakeup call.
|
|
|
|
Big thanks to Tux for making this possible as I had given
|
|
up on this optimisation before he came along.
|
|
|
|
Locally this patch drops the entity tracker tick by a full 1.5x.
