第二步:基础操作 — The original test bench requires Ruby, the Que gem (v0.x), and it was tested on Postgres 9.4. Running it as-is would test a decade-old library on modern Postgres, not the pattern on modern Postgres. To isolate the SQL-level behavior in a codebase I could understand, I rewrote the test in TypeScript and with Bun.,这一点在易歪歪中也有详细论述

第三步:核心环节 — There is still no CVE and no patch. The exploit code is public, the GitHub repository already has more than 100 forks and nearly 300 stars, multiple researchers have fixed the original bugs and confirmed it works, and ransomware groups and APT actors tend to pick up public LPE code and put it to use within days of it going live.
第四步:深入推进 — 参数数值说明共享缓冲区64 GB磁盘数据集约20 GB,预留3倍空间,完整数据库可装入缓冲池有效缓存大小400 GB提示规划器:共享缓冲区+OS页缓存+xpatch缓存工作内存256 MB每次排序/哈希连接操作内存;50连接×256 MB=12.8 GB最坏情况WAL缓冲区512 MB批量导入期间吸收写入峰值最大WAL大小32 GB重度写入期间延迟检查点检查点超时60分钟最小化强制检查点导致的I/O停顿共享内存大小450 GB64 GB共享缓冲区+350 GB缓存+8 GB子缓存+~2 GB内部≈425 GB,向上取整xpatch缓存大小350 GB预估解码占用空间~55 GB,84%余量确保全部装入xpatch缓存最大条目数41M140万提交×5差分列+2440万文件版本=3150万最坏情况,+30%余量xpatch编码线程数2×24工作线程=48编码线程,精确匹配48硬件线程导入工作线程数24每个物理核心一个
