织梦DedeCMS数据量达到万级后 生成速度很慢解决办法

织梦由于生成静态文件原因及系统架构本身的原因，当数量达到万级别后，生成栏目及文档相当缓慢，介绍下，通过改动系统文件来提升生成速度，修改以前请大伙做好织梦程序的备份。

1 | 先设置 关闭副栏目（在系统—-系统基本参数—性能选项里）

2 | 一般网站不需要 栏目交叉 交叉 所以 找到94行注释掉：

打开：include/arc.listview.class.php

找到以下代码并注释（注释代码为：/*代码*/）：

查看源码//获得交叉栏目ID            /*if($this->TypeLink->TypeInfos['cross']>0 && $this->TypeLink->TypeInfos['ispart']==0)            {                $selquery = '';                if($this->TypeLink->TypeInfos['cross']==1)                {                    $selquery = "SELECT id,topid FROM `dede58_arctype` WHERE typename LIKE '{$this->Fields['typename']}' AND id'{$this->TypeID}' AND topid'{$this->TypeID}'  ";                }                else                {                    $this->Fields['crossid'] = preg_replace('/[^0-9,]/', '', trim($this->Fields['crossid']));                    if($this->Fields['crossid']!='')                    {                        $selquery = "SELECT id,topid FROM `dede58_arctype` WHERE id in({$this->Fields['crossid']}) AND id{$this->TypeID} AND topid{$this->TypeID}  ";                    }                }                if($selquery!='')                {                    $this->dsql->SetQuery($selquery);                    $this->dsql->Execute();                    while($arr = $this->dsql->GetArray())                    {                        $this->CrossID .= ($this->CrossID=='' ? $arr['id'] : ','.$arr['id']);                    }                }            }*/

继续查找并注释：

//获得附加表的相关信息 /*$addtable  = $this->ChannelUnit->ChannelInfos['addtable'];        if($addtable!="")        {            $addJoin = " LEFT JOIN `$addtable` ON arc.id = ".$addtable.'.aid ';            $addField = '';            $fields = explode(',',$this->ChannelUnit->ChannelInfos['listfields']);            foreach($fields as $k=>$v)            {                $nfields[$v] = $k;            }            if(is_array($this->ChannelUnit->ChannelFields) && !empty($this->ChannelUnit->ChannelFields))            {                foreach($this->ChannelUnit->ChannelFields as $k=>$arr)                {                    if(isset($nfields[$k]))                    {                        if(!empty($arr['rename'])) {                            $addField .= ','.$addtable.'.'.$k.' as '.$arr['rename'];                        }                        else {                            $addField .= ','.$addtable.'.'.$k;                        }                    }                }            }        }        else        {            $addField = '';            $addJoin = '';        }*/
