先看负载复制的敏感性
8 MiB、空回调的独立 A/B：每次 1,000 万条，5 次平均；只改外部 Payload 复制构造，完整校验通过。
这是此前两种复制方式的独立实验，未使用本次新增的写预取；不计入本轮主表运行次数；记录时间：2026-10-11T00:16:44.565737+08:00。
本次正式表格固定采用 完整负载复制；rigtorp 可选目标写预取，ReaderWriterQueue 可选先清零再 memcpy。仅改变复制构造就能显著改变部分开源队列的结果。后面的差距包含负载类型与编译器代码生成的影响，不能将它全部算成队列算法的优势。具体处理器层面的原因尚未确定；默认复制构造的额外校验也未消除异常。

按消息长度查看吞吐
条形长度仅在同一消息长度内比较。单位 M条/s = 每秒百万条消息。
160 次正式测量16 次负载校验消息计数 / FIFO 校验通过写入失败为 0p999 样本量提示
TwoBufQueue 的第一层与第二层各 256 MiB，合计 512 MiB；三种开源 SPSC 请求 256 MiB。ReaderWriterQueue 会按内部块容量略微取整。
每种长度的回调业务循环次数固定，各实现共享；本轮未重新校准到 2～3 倍，表格保留实际时间比。
本次没有重新寻优，吞吐和各延时指标使用同一构造配置。普通 write 与 Session 的读端/发布配置和测量轮次可能不同，不能当作同参数对照。
只重新测量 normal 与三个开源对照；另一写模式的报告保持原样，没有把它的历史数据混入本轮主表。
每层数据池严格为 256 MiB；原生队列的保留槽与 rigtorp 首尾 padding 纳入这个 payload 存储预算，队列元数据和输入另计。
Session 正常遇到块满返回 insufficient_space，次数记入 session_block_exhaustions；这不是背压或丢消息。池/队列受压通过 Writer 内部压力统计报告。
rigtorp_write_prefetch 在完整参数中记录；开关在测试开始前选择模板，普通复制和带提示构造都只复制一次完整负载，不额外写零。atomic_queue 保持原有调用。
ReaderWriterQueue 16/32 B 使用 copy_after_zero：队列槽位默认清零后 memcpy 一次完整负载；8/64 B 保留成员复制。清零和复制均在写入计时内。各实现的调用端优化在行标签和完整参数中公开，不能把所有差异归因于队列算法。
256 MiB 回调循环按 8/16/32/64 B 固定为 1/1/2/4 次，本次未重新校准。用于控制读端/发布参数变化；实际时间比保留在表格中，不保证仍在 2～3 倍范围。
TwoBufQueue 8 B：is_scan_current=true, publish_count=10, 初始/最大扫描间隔=1000000/1000000 ns，最小等待=1 ms。
TwoBufQueue 16 B：is_scan_current=true, publish_count=10, 初始/最大扫描间隔=1000000/1000000 ns，最小等待=1 ms。
TwoBufQueue 32 B：is_scan_current=true, publish_count=10, 初始/最大扫描间隔=1000000/1000000 ns，最小等待=1 ms。
TwoBufQueue 64 B：is_scan_current=true, publish_count=10, 初始/最大扫描间隔=1000000/1000000 ns，最小等待=1 ms。
本轮只改变普通 write 的当前块扫描和发布参数；Session 的配置、报告和原始结果保持上一轮原样。三个开源对照本轮重新测量，未使用历史成绩替换。
256 MiB 的 1/1/2/4 次回调循环沿用 release_20261011_inline_fixed_110024；8 MiB 仍为 0。本次合计 320 次正式测量、32 次独立完整负载/FIFO 校验，没有重新校准或寻优。
测试框架增加 publish_count=10 的编译期 Writer 实例，并修正非 2 次幂发布次数的轮末自然发布对齐；未修改库 src/include 或第三方头文件。每轮少于 1000 条的尾部仍发送并记录，延时样本只统计完整的 1000 次写入组。

p50 / p99 / p999 是“每组 1000 次成功写入的平均耗时”的分位数，不是单条消息端到端延时，也不是单次 write 的分位数。吞吐使用独立的未逐组计时运行。GB/s 按业务净负载计算。时间比 = 各轮首条回调开始至末条回调结束的耗时之和 ÷ 各轮写线程发送耗时之和，再对运行取平均；它包含分发、等待数据和调度，不是每次回调函数 CPU 耗时之和。
回调时间与背压
与吞吐表使用同一批正式运行。时间、次数按运行取平均；峰值 RSS 为这组运行的最大值。

受压消息至少经历一次 try 写入失败；失败尝试含重复重试，最终仍全部写入。Writer 与复制层内部事件仅 TwoBufQueue 提供，其他实现显示“—”，不能把“—”解释为 0。回调区间含分发、轮内等待及调度，时间比大于 1 本身不等于写端背压。RSS 包含进程开销，不等于缓存容量。

测试口径与复现信息
固定本次参数进行对比；本报告没有执行全参数寻优，也不声称全局最优。
发送、复制与排空
TwoBufQueue：Writer → 复制线程 → 第二层缓存 → 独立回调线程，逐消息调用回调。
按长度保留冻结的块大小和每层容量。普通 write 与 Session 的读端及发布配置各自独立，完整参数如下。四种实现正式写入次数与净负载长度相同。
每轮上限按缓存的 80% / 消息字节数计算，再停在实际发布批次的整数倍位置。TwoBufQueue 开启当前块扫描，无逐条或轮末主动 flush。停止写线程计时后等待本轮全部回调完成；最终尾部由正常 finish 收尾。
两份报告同时改变缓存大小与回调工作量，不能将两组差异全部归因于缓存；比较容量影响需另做相同回调负载的对照。
扫描当前块 · 不主动 flush；publish_count 固定为 10。仅预触碰写端数据页，第二层数据页没有额外预触碰。
吞吐和分组延时均在计时前准备整轮输入；每条消息的全部字都随序号变化；四种实现使用同一完整负载；队列内仍复制一次完整负载；各行标明成员复制、目标写预取或先清零再 memcpy，完整参数记录实际选择；先清零的额外存储也包含在计时中。输入缓冲单独计算，不算队列容量，也不保证常驻 L1。
时钟、调度与限制
本机为 macOS-14.4.1-arm64-arm-64bit / arm64，Release 优化构建。
计时器：mach_absolute_time；每组 1000 次写入。组均值刻度约 0.0417 ns / 次。
写线程调度：高 QoS · 未硬绑核。调度打断和其他系统活动仍可能影响结果；复制与回调线程保留自身调度策略。
吞吐只累计写线程发送时间；排空在计时之外。并发复制 / 回调仍可能争用缓存和带宽，因此不是持续端到端吞吐。
p999 仅供观察：每次延时测量约有 9,998–10,000 个组均值样本，少于框架建议的 100,000 个。p999 的尾部覆盖有限，不能据此做稳定的尾延时承诺。p999 表示 99.9% 分位数；平均值不代表置信区间。
