Subject: [PATCH] Reduce sync loads
|
|
|
|
This reduces calls to getChunkAt which would load chunks.
|
|
|
|
This patch also adds a tool to find calls which are doing this, however
|
|
it must be enabled by setting the startup flag -Dpaper.debug-sync-loads=true
|
|
|
|
To get a debug log for sync loads, the command is /paper syncloadinfo
