适用于: Azure SQL 数据库 Azure SQL 数据库提供了内置工具,用于确定高 CPU 使用率的原因并优化工作负载性能。 可以使用这些工具在高 CPU 使用率出现时,或在事件完成后以被动方式对该问题进行故障排除。 还可以启用自动优化,以便随着时间推移主动降低数据库的 CPU 使用率。 本文说明如何在 Azure SQL 数据库中使用...
If the CPU usage,SQLCompilations/sec, and Free Buffers counters are high, and the Memory Grants Pending and Stolen Page Count counters are low, this indicates that the CPU is the bottleneck. Focus on how to effectively parameterize and reuse query plans to avoid the cost of query plan genera...
select USER,CURRENT_CONNECTIONS from performance_schema.users where CURRENT_CONNECTIONS >0 and USER not in ('NULL','azure_superuser'); 编写不当的 SQL 查询 在没有索引的情况下执行和扫描大量行的查询成本高昂,或者那些与其他低效计划一起执行临时排序的查询,都可能导致 CPU 峰值。 虽然某些查询可能在单个...
You can also use sqlcmd’s -a parameter and the free_entries_count column of the DMV changes for different packet size and pool usage scenarios. LEAVE: The 3rd SNIPacketAllocateEx2 is the return or exit from SNIPacketAllocateEx2 For the sake of this example assume that t...
