性能指标报告
这些会被保存为 zip 文件并存放于 debug/profiling/<yyyy-MM-dd_HH.mm.ss-[levelname]-[version]>.zip，附于问题汇报时可用于性能回归分析。
确切的指标、输出格式和名称会在不同版本间频繁变动。我们计划持续迭代关于收集指标的方案。
客户端 F3+L 快捷键
在游戏中按下 F3+L 会启动持续 10 秒的指标收集，包括刻时长、使用堆大小和其他更细节的统计数据。
在 10 秒内再次按下 F3+L 会提前结束收集。
这个快捷键在客户端中总是可用，在多人游戏中则会收集客户端的性能数据。
专用服务器 PERF START/STOP 命令
perf start 会启动持续 10 秒的指标收集，包括刻时长、使用堆大小和其他更细节的统计数据。
在 10 秒内执行 perf stop 可提前结束收集。
