看看我们网站首页的存储过程,不知道为什么首页访问速度这么慢.

都是select 和交叉链，首页缓存了没有？用缓存就不用每次都读数据库了，语句应该能再精简一些，一些地方可以用ajax来处理。另外可以用框架来处理一些地方

定时生成首页的静态页，
如果实时性和交互性不是那么强的说。

慢不一定是程序执行效率的问题，不过看你这个首页，用缓存比较好一些，甚至可以把HTML直接缓存起来定时更新
如果有缓存，SQL的效率显得不是“特别”重要了，不然，要好好优化SQL语句，优化索引等数据库元素，这是一项系统工程啊
/*顶部交易技能*/这个怕是会有问题，left join一不小心就会成为性能杀手
另外，看你where后面一堆的条件，不大可能快起来，一般首页推荐之类的东西其实不太要求实时更新，所以可以考虑在数据库中建立冗余表，然后跑作业进行定时更新，首页显示时直接从冗余表里取信息，会快很多，程序也好写

还是用数据缓存一下比较好
但也要看到底是多慢，打开页面慢 不一定都是还数据库操作的问题。

总的来说你还是好好在索引下功夫，如条件字段还有排序字段，按不同的要求建立聚集/非聚集，单一或者复合索引~~

1.先把查询字段建立一下索引.
2.如果还是不行,你只有生成静态页面了.

在一个存储过程中取出这么多数据？
这些数据的缓存时间一样吗？建议把这个存储过程拆开，缓存时间一样的放在一个存储过程中，对数据做缓存。
