From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Tue, 1 Mar 2016 23:09:29 -0600 Subject: [PATCH] Further improve server tick loop Improves how the catchup buffer is handled, allowing it to roll both ways increasing the effeciency of the thread sleep so it only will sleep once. Also increases the buffer of the catchup to ensure server stays at 20 TPS unless extreme conditions Previous implementation did not calculate TPS correctly. Switch to a realistic rolling average and factor in std deviation as an extra reporting variable diff --git a/src/main/java/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index 4d5a8c051ab7746ed40d5b79558e86238618827c..92eb6e80e3b6f74dd32a878e5436d338c89ea60e 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -285,7 +285,7 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop processQueue = new java.util.concurrent.ConcurrentLinkedQueue(); public int autosavePeriod; public Commands vanillaCommandDispatcher; @@ -294,7 +294,7 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop 5000L && this.nextTickTime - this.lastOverloadWarning >= 30000L) { // CraftBukkit long j = i / 50L; @@ -990,12 +1042,18 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop 0 && args[0].equals("mem") && sender.hasPermission("bukkit.command.tpsmemory")) { + sender.sendMessage(net.kyori.adventure.text.Component.text() + .append(net.kyori.adventure.text.Component.text("Current Memory Usage: ", net.kyori.adventure.text.format.NamedTextColor.GOLD)) + .append(net.kyori.adventure.text.Component.text(((Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) / (1024 * 1024)) + "/" + (Runtime.getRuntime().totalMemory() / (1024 * 1024)) + " mb (Max: " + (Runtime.getRuntime().maxMemory() / (1024 * 1024)) + " mb)", net.kyori.adventure.text.format.NamedTextColor.GREEN)) + ); + if (!this.hasShownMemoryWarning) { + sender.sendMessage(WARN_MSG); + this.hasShownMemoryWarning = true; + } } - sender.sendMessage( sb.substring( 0, sb.length() - 2 ) ); - sender.sendMessage(ChatColor.GOLD + "Current Memory Usage: " + ChatColor.GREEN + ((Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) / (1024 * 1024)) + "/" + (Runtime.getRuntime().totalMemory() / (1024 * 1024)) + " mb (Max: " - + (Runtime.getRuntime().maxMemory() / (1024 * 1024)) + " mb)"); + // Paper end return true; } - private String format(double tps) + private boolean hasShownMemoryWarning; // Paper + private static net.kyori.adventure.text.Component format(double tps) // Paper - Made static { - return ( ( tps > 18.0 ) ?
