A Discussion About Minecraft Server Configurations

Abstract

这篇文章将讨论如何对一个 Minecraft服务端 进行 基本配置，优化配置 以及一些进阶的内容。

我们将讨论如何在 减少对VANILLA做出改变 的情况下，对 服务端核心 进行性能优化。

这篇文章会从最基本的配置开始，并且逐渐介绍一些比较重要的 配置项。

当然，我们可能会略过一些无关影响的项目。

How to choose the best server-core ?

如何选择 服务端核心 取决于你的需求。

由于这篇文章主要侧重于针对 插件服 的优化讨论，所以我们不会过多地讨论 模组服 的优化问题。

对于 模组服 而言，更应当考虑的是 兼容性问题 和 安全性问题。

对于安装有多个 模组 的 模组服 而言，首要的任务是解决上述两个问题，然后再考虑解决 影响较大的性能问题。

目前来说，模组服可以选择两种主流的核心：

• 基于Forge + Bukkit 的核心：这类核心将同时支持 Bukkit 和 Forge 的 API，但或多或少存在不同的兼容问题，

  本质上来说，由于两套事件系统是相对独立的，如何较好地来处理EventBus一直是比较头疼的问题。

  如果你希望有较好的兼容性，可以尝试 CatServer

  如果你希望保持最新版本的更近，可以尝试 Mohist

  尽管 Mohist 的开发团队尽力地保持版本跟进，并且他们宣称拥有 99%的Bukkit插件兼容性，但事实并不是这样的。

  Mohist经常会出现莫名其妙的 NPE异常，并且对于部分 流行插件 仍具有兼容问题。

  一些已经停止维护的核心，如MCPC，KCauldron等，以及他们的接力者将不被提及。

• 基于 Forge/Fabric 的核心：如果你选择了这类核心，那么将免去了 插件 的那些麻烦事情。

  你可能将无法安装插件，但你或许根本不需要他们。

  使用 Mixin技术 的 Sponge 比较激进，但是如果它符合你的需求，可以做一个尝试。

  此外， Fabric 搭配 优化类模组 也是不错的选择。

对于 插件服 而言，我们将首先排除掉 Vanilla ，这是 Mojang 所提供的默认服务端 ，尽管它可以保证原汁原味的特性，但由于极其糟糕的性能表现，以及不支持 Bukkit API，将不符合大部分的需求。

其次考虑 CraftBukkit，最大的特色是加入了 Bukkit API 的支持，这构成了 插件服 的基础。

但如果你打算使用 CraftBukkit，请不妨考虑下 Spigot，后者拥有 更好的性能，并且对 特性的改变 与前者相差甚微。

接下来，我们会讲本篇文章的主角：Paper 是一个注重于 性能 与 安全 的 下一代服务端，在保持 较多特性 不被改变的情况下，提供了 极大的性能优化。

并且，你根本不需要担心 Bukkit API 的兼容性问题，甚至相反地，主流的插件 会主动选择使用提供了更多功能的 Paper API，而这一切都是 向下兼容的

插件开发者 应该尽量选择使用 Paper API，而不是 Spigot API。以便免费地获得 性能提升，同时不丢失 兼容性。

进一步地，Purpur 是一个 基于Paper的服务端，它提供 更进一步的性能优化，以及 更高自由度的配置项。

本文会着重讨论 Paper/Purpur 核心。

如果 Paper 已经完全足够满足你的需求，那么你可以选择就使用它。但 Purpur 仍然有许多有用的 特性开关，以及 性能优化

我知道有许多 基于Paper/Purpur的服务端，但 Paper/Purpur 已经提供了足够多的 保守的性能优化，以及一些 激进的性能优化。

在这个前提下，选择 其他更进一步的优化端，将很难获得 显著的性能提升，并且将引入更多的 不稳定性。

How to config the server-core ?

这个章节将占据大部分的内容，而且也是 最重要 的，或许也是 最难的。

重新强调一遍，本篇文章基于的原则是：最小化对VANILLA的改变的同时，尽可能地获得优化配置。

优化配置 是糟糕的方案，他们本应该在 代码 中完成优化，那样才会是最有效的。

我们会循序渐进地讨论每个配置项。

How to analyse profile reports ?

如果你在 服务端核心 处于 laggy 状态的时候进行 采样，那么结论往往是：tick entity 和 tick chunk 将占据最多的 计算量。

对于 tick chunk 而言，你能做的事情其实很有限。

可以通过修改 tick-per 中的 monter-spawn 来大幅度减少 tick chunk 的 计算量。

但这么做取决于你的需求。

对于 tick entity 而言，你需要根据 报告 所指出的 异常指标 ，对 behavior 和 sensor 进行调整。

这里列出几个需要特别注意的实体：villager， zombified_piglin， illager

对于 villager 而言，可以通过修改 acquirepoi 来显著地减少计算量，但这会导致 寻路算法 的执行频率降低。

而 validatenearbypoi 会影响对 工作方块 的 识别速度。

如果此时有多个 劫掠塔 在运行，则可以发现 victorystroll 的计算量显著上升。

如果你希望 runone 的平均值降低，则可以修改 dab 或者 lagging-threshold，但是这将会影响 villager 的 全部的 behavior 和 sensor。

一般不建议这么做。

请注意，某个entity的gravity计算 是包括在 该entity的AI计算 之中的。

entity 有自己 内置的tick 来进行 AI计算，它不受 外部的tick 影响。

对于 zombified_piglin 而言，主要是2个原因导致 计算量 偏高。

• 联动仇恨
• 高刷怪效率

即使 zombified_piglin 被 高效率地处置，仍然会 持续占据 这部分 计算量。

Paper早已修复了由于 player 跨越 dimension 使得 zombified_pigin 因为 raytrace 错误计算而导致的 追踪射线沿途的大量区块被错误地加载 造成的卡顿问题。

对于 bee 来说，曾经也存在类似的问题，但目前已经被修复。

对于 illeger 来说，情况和 zombified_piglin 类似。

区别在于 单座劫掠塔 一般比 单座猪人塔 的 刷怪效率更低，而且 刷怪效率 呈现 锯齿形波动。

如果你只看到了 pillager 偏高，那么原因可能是其在野外环境的 自然生成 占用 计算量，该BUG可以通过升级版本修复。

关于 性能采样器，这里使用 Timings v2 进行性能分析（这是Paper所提供的）。

如果你使用的是Purpur，那么非常建议你使用 Spark 进行分析，它比 Timings v2 更加优秀。

• 更美观的UI
• 更易读的报表
• 更好的性能
• 更细的采样粒度

Plugins 不应当占据过多的 计算量。如果某个 Plugin 占据了太多计算量，那么你应该考虑弃用它，或者选择一个替代品。

并不是所有的开发者都会在编写代码的时候，时刻关注高性能。

Player实体 并不真正地占用 计算量，他们甚至不如 Villager实体 占用的 计算量 高。

Entity 占用计算量的真实原因是，他们需要为 AI计算 付出 高额的代价 （往往的 寻路算法，也包括部分敏感的 传感器 (Sensor)）。

单个 Entity 越聪明，则占用的 计算量 越大。（毫无疑问，Villager 是最聪明的实体，此外，Zombie 族 实体由于存在 与Villager的威胁关联，所以其 AI计算也会比其他实体更高）

Tile Entity 占用的 计算量 远少于 Entity。

尽管 Paper 针对 hopper 有优化算法，但是由于 hopper 的数量一般较多，在报告结果中，hopper 仍然可能是 计算量 最高的 Tile Entity。

Chest ，Furnace 和 Sign 对 计算量 的占用极小，但是他们的渲染可能会导致客户端卡顿。

Observer 以及 单纯的时钟电路 并不占用多少 计算量，一般取决于这个结构的 输出端 在做什么。

但 Piston ，特别是 Sticky Piston 则非常占用 计算量。

这是因为他们每次的 激活 与 失活 均会造成 方块更新，同时会产生 Moving-Piston 这个 Tile Entity

通过使用拥有更高睿频和IPC的CPU虽然对提升性能有所帮助，但性价比极低。

Vanilla 从一开始就没有考虑过 多线程任务，并且也不是针对 multi-player games （个位数以上的玩家）设计的。

后续的核心很难在维持 Vanilla 的同时，实现 多线程任务。

大部分情况下，CPU的利用率 仅仅维持在 5-15% 之间。

这里提供一个有效且相对可以接受的软件解决思路：

根据 上下文 来选择性地限制 实体 的 行为 和 传感器。

目前已经有一些 插件方案 使用这个思路，尽管他们使用的 具体策略 不同。

对性能的优化较为显著甚至明显，但对 vanilla 的破坏较少。

比较有知名度的 anti-villager 没有考虑上下文和控制粒度，但实际上 villager 的控制粒度可以更细。

而 farm-limiter 虽然很早就使用该思路，但是对 上下文 的判定选项不够精准。

How to choose plugins ?

这个章节不太应该属于本文，这里选择仅讨论一小部分的 Anti-Cheat 。

对于 plugin 选择，一般考虑：

• 功能足够简单，但满足需求
• 可配置度高
• 没有造成卡顿的Events

这两个原则大部分情况是对的：

• 服务端核心可以做的事情，不要用插件。
• 1个插件可以做的事情，不要用2个插件去完成。

难以遵守这两个原则的主要原因是：维护者自己根本不清楚 core 和 plugin 到底有什么职责。

Anti-Cheat Review

bypass 是不可避免的，这是协议的缺陷。

• NCP：开源，最好搭配其他AC使用，适合魔改。
• Vulcan：较高的可配置性，适合Survival，默认不启用setback。（已经有full-bypass了）
• Matrix：开箱即用，配置比Vulcan简单，Movement和Timer没什么问题，Premium版新增对Scaffold的额外检测，但KillAura检测存在缺陷。
• Spartan：不推荐，FP 和 FN 指标都不好看。
• GrimAC：值得尝试，开源，对Reach，Movement，Timer的检测精度较高，但Scaffold检测存在缺陷。
• Intave：看需求，可能不适合Survival，目前存在较多的致命FP尚未解决。但是对于Mini-Game是合适的。
