Subject: [PATCH] Remove the Vanilla Method Profiler
|
|
|
|
Spigot rebrought this back after it was removed for years due to the performance hit.
|
|
|
|
It is unknown if the JIT will optimize it out as effeciently with how it was
|
|
added, so we do not want any risk of performance degredation.
|
|
|
|
Paper has a proper Timings system that makes the Vanilla Method profiler obsolete and inferior.
