At the time this was re-added, there was concern around how the JIT would handle the system property that enabled it. This shouldn't be a problem, and as such we no longer need to block access to it. The Vanilla Method Profiler will not provide much to most users however there is no harm in providing it as an option. For most users, the recommended and supported method for determining performance issues with Paper will continue to be Timings.

Subject: [PATCH] Don't blindly send unlit chunks when lighting updates are
|
|
allowed
|
|
|
|
Spigot, by default, disables several mechanisms around how chunks are
|
|
lit, if ever, which has forced them to always send chunks before vanilla
|
|
would consider them ready to send, causing for lots of issues around
|
|
lighting glitches.
|
|
|
|
Shamefully, the amount of work to relight chunks can be detremental
|
|
to some servers, meaning that forcibily disabling light updates can
|
|
cause major performance issues.
|
|
|
|
as such, we make a compromise; if this "feature" is disabled, we will
|
|
only send chunks which are actually ready to be sent, otherwise, we
|
|
will always send chunks.
