ECSHOP网店上万商品量性能优化-加快首页访问速度

如果ECshop的商品数达到几万，十几万的时候，如果首页没有缓存，第一次访问的时候，你会发现其慢无比，原因就是清空了Cache后或者没有Cache的情况下，ECshop会Bulid一些Cache数据，导致访问很慢，但我们有时候后台编辑类目或者其他的，经常会触发清空Cache，所以首页首次访问也成了问题。 在大数据量的情况下，影响首页速度最大的就是推荐的Best、Hot、New Item的数据Bulid，它会把所有的复合条件的商品都会读一遍，然后存到/temp/static_caches/recommend_goods.php这个文件下，有时候会达到10M或者数十M，其实我们并不需要所有的商品都Bulid进去，因为这个缓存只用在首页和Category页的调用，有点浪费。（P.S 因为Category访问本来就比较慢，所以我把热卖商品在Category的展示屏蔽了，所以只剩首页调用） 首页展示的时候，三种类型Best、Hot、New只展示10个商品（没有选择展示多个类目），所以这个上面有很大的优化空间。 打开include目录下的lib_goods.php文件，找到function get_recommend_goods() 函数，原始的大概是： /** * 获得推荐商品 * * @access public * @param string $type 推荐类型，可以是 best, new, hot * @return array */ function get_recommend_goods($type = \'\', $cats = \'\') { if (!in_array($type, array(\'best\', \'new\', \'hot\'))) { return array(); } //取不同推荐对应的商品 static $type_goods = array(); if (empty($type_goods[$type])) { //初始化数据 $type_goods[\'best\'] = array(); $type_goods[\'new\'] = array(); $type_goods[\'hot\'] = array(); $data = read_static_cache(\'recommend_goods\'); if ($data === false) { $sql = \'SELECT g.goods_id, g.is_best, g.is_new, g.is_hot, g.is_promote, b.brand_name,g.sort_order \' . \' FROM \' . $GLOBALS[\'ecs\']->table(\'goods\') . \' AS g \' . \' LEFT JOIN \' . $GLOBALS[\'ecs\']->table(\'brand\') . \' AS b ON b.brand_id = g.brand_id \' . \' WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 AND (g.is_best = 1 OR g.is_new =1 OR g.is_hot = 1)\'. \' ORDER BY g.sort_order, g.last_update DESC\'; $goods_res = $GLOBALS[\'db\']->getAll($sql); //定义推荐,最新，热门，促销商品 $goods_data[\'best\'] = array(); $goods_data[\'new\'] = array(); $goods_data[\'hot\'] = array(); $goods_data[\'brand\'] = array(); if (!empty($goods_res)) { foreach($goods_res as $data) { if ($data[\'is_best\'] == 1) { $goods_data[\'best\'][] = array(\'goods_id\' => $data[\'goods_id\'], \'sort_order\' => $data[\'sort_order\']); } if ($data[\'is_new\'] == 1) { $goods_data[\'new\'][] = array(\'goods_id\' => $data[\'goods_id\'], \'sort_order\' => $data[\'sort_order\']); } if ($data[\'is_hot\'] == 1) { $goods_data[\'hot\'][] = array(\'goods_id\' => $data[\'goods_id\'], \'sort_order\' => $data[\'sort_order\']); } if ($data[\'brand_name\'] != \'\') { $goods_data[\'brand\'][$data[\'goods_id\']] = $data[\'brand_name\']; } } } write_static_cache(\'recommend_goods\', $goods_data); } else { $goods_data = $data; } $time = gmtime(); $order_type = $GLOBALS[\'_CFG\'][\'recommend_order\']; //按推荐数量及排序取每一项推荐显示的商品 order_type可以根据后台设定进行各种条件显示 static $type_array = array(); $type2lib = array(\'best\'=>\'recommend_best\', \'new\'=>\'recommend_new\', \'hot\'=>\'recommend_hot\'); if (empty($type_array)) { foreach($type2lib as $key => $data) { if (!empty($goods_data[$key])) { $num = get_library_number($data); $data_count = count($goods_data[$key]); $num = $data_count > $num ?
