Dedecms V3.1 生成HTML速度的优化办法
由于版本兼容性等各方面的原因,实际上dedecms的索引有点混乱,如果索引设置得适合,影响dedecmsHTML生成速度的,主要是获得没有按默认按排序的文章列表的时候,由于要重新排序,数据量大时速度会很不理想,可以通过下面几个步骤轻松优化:
1、进入 phpmyadmin ,把 dedecms 站点 dede_archives 除了 ID 主键的索引外的索引删除;
2、用SQL创建如下索引:
Alter TABLE `dede_archives` ADD INDEX `click` (`click`);
Alter TABLE `dede_archives` ADD INDEX `typeid` (`typeid`);
Alter TABLE `dede_archives` ADD INDEX `arcrank` (`arcrank`);
Alter TABLE `dede_archives` ADD INDEX `sortrank` (`sortrank`);
Alter TABLE `dede_archives` ADD INDEX `senddate` (`senddate`);
Alter TABLE `dede_archives` ADD INDEX `pubdate` (`pubdate`);
Alter TABLE `dede_archives` ADD INDEX `litpic` (`litpic`);
Alter TABLE `dede_archives` ADD INDEX `typeid2` (`typeid2`);
在数据量为1W-10W左右的区间,经过这样的优化后,如果内容页没有相关文章的标记,生成速度会快三至五倍
如果有相关文章标记,也会快两至三倍
