摘要

5 轮场景累计 35,827 请求：零失败、零 429、零 5xx、零业务错误。
读路径容量裕度 ≥2 个数量级：600 RPS 突发（约为当前请求量的数千倍）仍全部成功，p95 1.05s。
首个瓶颈为 2 核共享 CPU（突发段 load 5.44，四容器合计 ~147%/200%）；内存非首要约束。

结果总览

场景	负载	请求	失败/429	p50	p95	max
dev 匿名读 L1	15 RPS 阶梯 ×3 段	900	0 / 0	162ms	571ms	2.72s
dev 匿名读 L2	60 RPS 阶梯 + 120 突发 30s	6,082	0 / 0	169ms	858ms	3.33s
dev 匿名读 L3	300 RPS 阶梯 + 600 突发 30s	27,432	0 / 0	253ms	1,052ms	13.4s*
dev 认证读写	3 RPS 读 + 写序列（1 帖/2 回/16 互动）	199	0 / 0	90ms	478ms†	1.34s
prod 只读摸底	20 RPS 阶梯 + 40 突发 15s	1,214	0 / 0	176ms	660ms	3.15s

* 尾部为客户端 VU 池（200）排队所致，非服务端错误。 † 认证读 p95。

600 RPS 突发段服务器峰值（15:52–15:53）：load 5.44（基线 0.11）· dev CPU 61% · PG 54% · Meili 29% · main 3% · 内存最低 avail 525MB（基线 765MB）。

图1-p95延迟阶梯

图2-服务器资源峰值

图3-吞吐与错误率

关键发现

容量：持续 300–600 RPS 为实际饱和区间；突发靠内核排队全量吸收，无拒绝。当前业务规模下裕度约 2 个数量级。
瓶颈：CPU 先于内存饱和；SSR 模板渲染 + PG 查询 + gzip 为主要消耗方。内存最低仍有 525MB 可用。
延迟形态：p50 仅从 162ms 升至 253ms，p95 退化主要来自排队而非单请求变慢；CF TLS 往返构成 ~250ms 底座。
防护层：应用限流读配额（60–120/min/IP）在 40 RPS 单 IP 下未触发；新账号验证码墙与写配额按设计生效（压测刻意保持在墙内）。
内存行为：Go 服务 MADV_FREE 懒归还（main VmRSS 已回落至 72MB，峰值水位 VmHWM 156MB 不缩属正常）；Meilisearch 压测后驻留 ~180MB 为分配器保留（anon=178MB 稳定平台期，restart 即回 ~50MB）。
