From 7818de038076bd8bb1b44dc3fb2359ef59935ae3 Mon Sep 17 00:00:00 2001 From: md_5 Date: Fri, 13 Dec 2013 11:58:58 +1100 Subject: [PATCH] Configurable Amount of Netty Threads This brings back the option that the Spigot version of netty saw. By default Netty will try and use cores*2 threads, however if running multiple servers on the same machine, this can be too many threads. Additionally some people have 16 core servers. If 32 Netty threads are allowed in this setup, then the lock contention, and thus blocking between threads becomes much greater, leading to decreased performance. diff --git a/src/main/java/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index 1e83999..94da13d 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -51,7 +51,7 @@ public abstract class MinecraftServer implements ICommandListener, Runnable, IMo private final List m = new ArrayList(); private final ICommandHandler n; public final MethodProfiler methodProfiler = new MethodProfiler(); - private final ServerConnection o; + private ServerConnection o; // Spigot private final ServerPing p = new ServerPing(); private final Random q = new Random(); private String serverIp; @@ -106,7 +106,7 @@ public abstract class MinecraftServer implements ICommandListener, Runnable, IMo i = this; this.c = proxy; // this.universe = file1; // CraftBukkit - this.o = new ServerConnection(this); + // this.o = new ServerConnection(this); // Spigot this.n = new CommandDispatcher(); // this.convertable = new WorldLoaderServer(file1); // CraftBukkit - moved to DedicatedServer.init this.S = (new YggdrasilAuthenticationService(proxy, UUID.randomUUID().toString())).createMinecraftSessionService(); @@ -1227,7 +1227,7 @@ public abstract class MinecraftServer implements ICommandListener, Runnable, IMo } public ServerConnection ag() { - return this.o; + return ( this.o ) == null ? this.o = new ServerConnection( this ) : this.o; // Spigot } public boolean ai() { diff --git a/src/main/java/org/spigotmc/SpigotConfig.java b/src/main/java/org/spigotmc/SpigotConfig.java index 08bd5ba..cfddd28 100644 --- a/src/main/java/org/spigotmc/SpigotConfig.java +++ b/src/main/java/org/spigotmc/SpigotConfig.java @@ -191,4 +191,11 @@ public class SpigotConfig } bungee = getBoolean( "settings.bungeecord", false ); } + + private static void nettyThreads() + { + int count = getInt( "settings.netty-threads", 4 ); + System.setProperty( "io.netty.eventLoopThreads", Integer.toString( count ) ); + Bukkit.getLogger().log( Level.INFO, "Using {0} threads for Netty based IO", count ); + } } -- 1.8.3.2
