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 7ae4d4feb5c9281fa62a3f35c39eefdff1b684d8..cf9ce8a8e7d576d91e9d745e9c45f698100808bd 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -289,7 +289,7 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop processQueue = new java.util.concurrent.ConcurrentLinkedQueue(); public int autosavePeriod; public Commands vanillaCommandDispatcher; @@ -298,7 +298,8 @@ 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 ) ?
