Subject: [PATCH] Consolidate flush calls for entity tracker packets
|
|
|
|
Most server packets seem to be sent from here, so try to avoid
|
|
expensive flush calls from them.
|
|
|
|
This change was motivated due to local testing:
|
|
|
|
- My server spawn has 130 cows in it (for testing a prev. patch)
|
|
- Try to let 200 players join spawn
|
|
|
|
Without this change, I could only get 20 players on before they
|
|
all started timing out due to the load put on the Netty I/O threads.
|
|
|
|
With this change I could get all 200 on at 0ms ping.
|
|
|
|
(one of the primary issues is that my CPU is kinda trash, and having
|
|
4 extra threads at 100% is just too much for it).
|
|
|
|
So in general this patch should reduce Netty I/O thread load.
