Those familiar with System I and database query performance analysis and tuning, understand that controlling the optimization goal is a critical step to optimizing performance.
那些熟悉systemi和数据库查询性能分析和调优的人就会理解控制优化目标是优化性能的关键步骤。
Tasks include planning and administering the database, tuning for performance and capacity, creating and maintaining indexes and optimizing queries, monitoring, and managing backup and recovery.
任务包括计划并管理数据库、调优性能与容量、创建和维护索引并优化查询、监测、以及管理备份与恢复。
Another GC tuning trap is focusing too much on reducing the headline GC overhead figure (see figure 7) and forgetting that the overall goal is optimizing application performance.
另一个gc调优陷阱是过度关注减小headline GC开销(参见图7)，而忘记了总体目标是优化应用程序的性能。
But as with all other performance-tuning activities, measure and positively identify problems before optimizing.
但是，和其他性能优化操作一样，我们需要在优化前先测量并确认问题所在。
