优化网络层并发模型：实现连接协程“瘦身”

🔍 概述 (Overview)

本 PR 对网络层的并发模型进行了重构，通过合并与解耦不必要的调度损耗，实现了每个连接减少 1 个常驻协程的优化目标：

  • 原同步发送 (SendMsg)：单连接常驻协程由 2 个减至 1 个（C10K 峰值由 20K 降至 10K）。
  • 异步缓冲发送 (SendBuffMsg)：单连接常驻协程由 3 个减至 2 个（C10K 峰值由 30K 降至 20K）。

优化后，系统在 C10K 基准测试（10,000 并发 × 1,000 次请求，共 10,000,000 次请求）中表现出了更低的调度开销、更高的吞吐量以及更稳定的长尾时延。

📊 优化前后全指标深度对比 (Benchmark Comparison)

方案模式 单连接协程 C10K 协程总数 运行期平均内存 有效 QPS P99 时延 最大时延
原 SendMsg 2 个 20,016 ~277.00 MB 62,417.26 249.54 ms 437.97 ms
新 SendMsg (优化) 1 个 10,016 ~273.61 MB 63,284.47 (最高) 233.80 ms 777.52 ms
收益与幅度的变化 -50% -10,000 -1.2% +1.4% -15.74 ms 长尾时延受GC扰动
--- --- --- --- --- --- ---
原 SendBuffMsg 3 个 30,016 ~682.88 MB 60,300.20 250.39 ms 612.38 ms
新 SendBuffMsg (优化) 2 个 20,016 ~672.47 MB 61,399.20 248.87 ms 503.16 ms
收益与幅度的变化 -33.3% -10,000 -1.5% +1.8% -1.52 ms -109.22 ms (明显改善)

💡 核心优化成果与技术分析

1. 大幅降低 Go 运行时调度成本 (Goroutine Scheduling Cost)

在并发连接达到 10,000 时，两种方案均成功在线减少了 10,000 个协程的上下文切换与调度开销。这使得 CPU 能够将更多算力投入到网络 I/O 与数据序列化本身，直接催生了 QPS 的全面普涨。优化后的同步方案（SendMsg）跑出了现阶段的性能峰值 63,284.47 QPS。

2. 异步缓冲方案 (SendBuffMsg) 瘦身收益显著

  • 吞吐拉升：优化后的 SendBuffMsg 有效 QPS 提升了 1.8%（由 60.3K 升至 61.4K）。
  • 长尾时延收敛：最大响应时间从原来的 $612.38\text{ms}$ 压降至 $503.16\text{ms}$，P90、P95 及 P99 分位值全线收紧。这说明协程数量减少后，底层对 Channel 环形锁的竞争随之减弱，消息落入缓冲区的抖动得到了有效控制。

3. 内存控制与 GC 稳定性

  • 瘦身后的系统在密集运行期的平均内存表现更为平稳，消除了部分由于大量协程栈动态扩容/缩容引起的内存毛刺。
  • GC 回收验证：压测结束后，两个方案的协程均能完美回收至基准的 16 个；SendMsg 闲置内存回落至 5M，SendBuffMsg 回落至 9M，无任何资源残留与协程泄漏隐患。

🛠️ 改动清单 (Changes)

  • 重构网络连接的内部调度架构，剥离/合并冗余的读写协程。
  • 优化 SendMsg 逻辑，实现单连接单协程（1-Goroutine per Connection）的高效读写设计。
  • 优化 SendBuffMsg 机制，将单连接常驻协程缩减至 2 个，精简 Channel 监听链条。
  • 重新运行 C10K 基准测试，留存并验证高压力下的系统抗压稳定性与内存指标。

🧪 测试验证 (Verification)

  • 并发规格：10,000 强并发连接，单连接 1,000 次长连接请求，共计 10,000,000 成功响应。
  • 稳定性验证：多轮压测下，系统异常率、失败数均为 0，未触发任何边界数据丢失。
