Subject: [PATCH] Lazily track plugin scoreboards by default
|
|
|
|
On servers with plugins that constantly churn through scoreboards, there is a risk of
|
|
degraded GC performance due to the number of scoreboards held on by weak references.
|
|
Most plugins don't even need the (vanilla) functionality that requires all plugin
|
|
scoreboards to be tracked by the server. Instead, only track scoreboards when an
|
|
objective is added with a non-dummy criteria.
|
|
|
|
This is a breaking change, however the change is a much more sensible default. In case
|
|
this breaks your workflow you can always force all scoreboards to be tracked with
|
|
settings.track-plugin-scoreboards in paper.yml.
