Subject: [PATCH] Player lookup improvements
|
|
|
|
Minecraft and CraftBukkit both use Arrays to store online players,
|
|
and any time a player needs to be looked up by name or UUID,
|
|
the system iterates all online players and does a name or UUID comparison.
|
|
|
|
This is very ineffecient and can reduce performance on servers with high player count.
|
|
|
|
By using a map based approach for player lookups, player lookup should
|
|
be consistent in performance regardless of how many players are online.
