Adjust dirty page parameters. In scenarios where doublewrite is enabled, you can adjust parameters such as **pagewriter\_sleep** (downward adjustment) and **max\_io\_capacity** (upward adjustment) to improve dirty page elimination efficiency. 3. Replace high-performance disks (such as NVMe disks). The resources occupied by the database must meet the service requirements. In a high-concurrency test, you need to add resources to ensure that database services are available. diff --git "a/content/zh/docs/DatabaseOMGuide/TPCC\351\253\230\345\271\266\345\217\221\351\225\277\347\250\263\350\277\220\350\241\214\345\233\240\350\204\217\351\241\265\345\210\267\347\233\230\346\225\210\347\216\207\345\257\274\350\207\264\346\200\247\350\203\275\344\270\213\351\231\215.md" "b/content/zh/docs/DatabaseOMGuide/TPCC\351\253\230\345\271\266\345\217\221\351\225\277\347\250\263\350\277\220\350\241\214\345\233\240\350\204\217\351\241\265\345\210\267\347\233\230\346\225\210\347\216\207\345\257\274\350\207\264\346\200\247\350\203\275\344\270\213\351\231\215.md" index a0f9762aa21ae1b6e43c5a2b7e8f0624409d4ea4..b08be05f11883cee2c15e92894a182302bf1cf86 100644 --- "a/content/zh/docs/DatabaseOMGuide/TPCC\351\253\230\345\271\266\345\217\221\351\225\277\347\250\263\350\277\220\350\241\214\345\233\240\350\204\217\351\241\265\345\210\267\347\233\230\346\225\210\347\216\207\345\257\274\350\207\264\346\200\247\350\203\275\344\270\213\351\231\215.md" +++ "b/content/zh/docs/DatabaseOMGuide/TPCC\351\253\230\345\271\266\345\217\221\351\225\277\347\250\263\350\277\220\350\241\214\345\233\240\350\204\217\351\241\265\345\210\267\347\233\230\346\225\210\347\216\207\345\257\274\350\207\264\346\200\247\350\203\275\344\270\213\351\231\215.md" @@ -11,7 +11,7 @@ TPCC高并发长稳运行因脏页刷盘效率导致性能下降,具体表现 ## 处理方式 1. 降低并发度或者调大shared_buffers参数。 -2. 调整脏页参数:在开启双写的场景下,可以调整page_writer_sleep(下调)、max_io_capacity(上调)等参数,加快脏页淘汰效率。 +2. 调整脏页参数:在开启双写的场景下,可以调整pagewriter_sleep(下调)、max_io_capacity(上调)等参数,加快脏页淘汰效率。 3. 更换高性能磁盘(NVME等)。 数据库占用资源应与业务需求相吻合。对于高并发测试中,需要增加资源以保证数据库业务可用。
