Subject: [PATCH] Add debug for sync chunk loads
|
|
|
|
This patch adds a tool to find calls to getChunkAt which would load
|
|
chunks, 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
|
|
- To clear clear the currently stored sync load info, use
|
|
/paper syncloadinfo clear
|
