8.2.1 Optimizing SELECT Statements[译]

1、在where子句中设置索引加快查询，及构造一个小的索引集合避免浪费磁盘空间。2、减小表扫描数量，特别是大表。3、保存表统计信息,以便优化器来构造一个有效的执行计划。4、学习调优技巧，索引技巧，及配置参数，特别是每个表的存储引擎配置参数。5、隔离和优化查询的每个部分，例如优化一个函数的调用所花时间，因为这样一个函数在一次查询中可能会调用数百万次。6、避免弄一些很难理解的查询转换，特别是优化器自动

Optimizing Layout Hierarchies

1，尽量少的嵌套   使用RelativeLayout代替 linearLayout   可以直接指定Item之间的关系，而不是使用嵌套的方式指定2，谨慎使用Layout_weight    会进行measured2次；3，使用布局测量工具HierarchyViewer   需要手机root4，使用lint   会提示布局错误；

《Tips for Optimizing C/C++ Code》译文

前不久在微博上看到一篇很好的短文讲如何对C/C++进行性能优化，虽然其面向的领域是图形学中的光线跟踪，但是还是具有普遍的意义，将其翻译成中文，希望对大家写高质量代码有帮助。1.     牢记阿姆达尔定律：加速比==其中表示函数func运行时间占总时间的百分比，表示对该函数加速获得的加速比。例如，你优化一个函数TriangleIntersect()，该函数的运行时间占总时间的40%，优化之后运行时间
