Subject: [PATCH] Replace player chunk loader system
|
|
|
|
The old one has undebuggable problems. Rewriting seems
|
|
the most sensible option.
|
|
|
|
This new player chunk manager will also strictly rate limit
|
|
chunk sends so that netty threads do not get overloaded, whether
|
|
it be from the anti-xray logic or the compression itself.
|
|
|
|
Chunk loading is also rate limited in the same manner, so this
|
|
will result in a maximum responsiveness for change.
|
|
|
|
Config:
|
|
```
|
|
chunk-loading:
|
|
min-load-radius: 2
|
|
max-concurrent-sends: 2
|
|
autoconfig-send-distance: true
|
|
target-player-chunk-send-rate: 100.0
|
|
global-max-chunk-send-rate: -1
|
|
enable-frustum-priority: false
|
|
global-max-chunk-load-rate: -1.0
|
|
player-max-concurrent-loads: 4.0
|
|
global-max-concurrent-loads: 500.0
|
|
```
|
|
|
|
min-load-radius - The radius of chunks around a player that
|
|
are not throttled for loading. The number of chunks
|
|
affected is actually the configured value plus one as this
|
|
config controls the chunks the client will be able to render.
|
|
|
|
max-concurrent-sends - The maximum number of chunks that
|
|
can be queued to send at any given time. Low values
|
|
are generally going to solve server-sided networking
|
|
bottlenecks like anti-xray and chunk compression. Client
|
|
side networking is unlikely to be helped (i.e this wont help
|
|
people running off McDonald's wifi).
|
|
|
|
autoconfig-send-distance - Whether to try to use the client's
|
|
view distance for the send view distance in the server. In the
|
|
case that no plugin has explicitly set the send distance and
|
|
the client view distance is less-than the server's send distance,
|
|
the client's view distance will be used. This will not affect
|
|
tick view distance or no-tick view distance.
|
|
|
|
target-player-chunk-send-rate - The maximum chunk send rate
|
|
an individual player will have. -1 means no limit
|
|
|
|
global-max-chunk-send-rate - The maximum chunk send rate for
|
|
the whole server. -1 means no limit
|
|
|
|
enable-frustum-priority - Whether chunks in front of a player
|
|
are prioritised to load/send first. Disabled by default
|
|
because the client can bug out due to the out of order
|
|
chunk sending.
|
|
|
|
global-max-chunk-load-rate - The maximum chunk load rate
|
|
for the whole server. -1 means no limit
|
|
|
|
player-max-concurrent-loads and global-max-concurrent-loads
|
|
The maximum number of concurrent loads for the server is
|
|
determined by the number of players on the server multiplied by the
|
|
`player-max-concurrent-loads`. It is then limited to
|
|
whatever `global-max-concurrent-loads` is configured to.
