This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.
We also store counts by type to further enable other performance optimizations in later patches.
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.
This will force the saves to spread over multiple ticks even when many
players auto save interval is aligned, avoiding spikes on large servers.
Closes#1021
- Lots of itemstack cloning removed. Only clone if the item is actually moved
- Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
- Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
- Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration
In Java 8u141 (1.8.0_141-b15) and newer, the
com.sun.management.HotSpotDiagnostic::dumpHeap API has changed and now
requires all heap dumps to end with the .hprof file extension.
Before this change, servers running 8u141 would be unable to perform a
heap dump.
For more information, please see the official release notes of Java 8
Update 141, linked below.

To dump the server heap, run the following command:
`/paper heap`
This is added with the intent that it is useful for administrators and
developers to more easily identify and resolve memory leaks. Both by examining
these dumps themselves and by more easily allowing them to send them to
knowledgable parties.
This is a nearly line-for-line port of the same Sponge feature. So all
credit for the idea and implementation belongs to the that team.
