ECshop网店系统百万级商品量性能优化-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(我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:
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 ' .

我的思路就是不读取所有的商品信息,而是Best、Hot、New够用展示就行了,所以把代码调整了一下,限制了Bulid的商品数,去掉了一些我不需要的Join表,当然大家不一定要照着我做,我讲的都是思路,看自己的实际情况,要有点程序基本功。
更改后的代码如下:
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.sort_order ' . ' FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' . ' WHERE (g.is_best = 1)'. ' ORDER BY g.goods_number DESC limit 50'; $goods_res = $GLOBALS['db']->getAll($sql); $goods_data['best'] = array(); if (!empty($goods_res)) { foreach($goods_res as $data) { $goods_data['best'][] = array('goods_id' => $data['goods_id'], 'sort_order' => $data['sort_order']); } } $sql = 'SELECT g.goods_id, g.sort_order ' . ' FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' . ' WHERE (g.is_new = 1 and g.is_best = 0 and g.is_hot = 0)'. ' ORDER BY g.goods_id DESC limit 50'; $goods_res = $GLOBALS['db']->getAll($sql); $goods_data['new'] = array(); if (!empty($goods_res)) { foreach($goods_res as $data) { $goods_data['new'][] = array('goods_id' => $data['goods_id'], 'sort_order' => $data['sort_order']); } } $sql = 'SELECT g.goods_id, g.sort_order ' . ' FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' . ' WHERE (g.is_hot = 1 and g.is_best = 0)'. ' ORDER BY g.goods_number DESC limit 50'; $goods_res = $GLOBALS['db']->getAll($sql); $goods_data['hot'] = array(); if (!empty($goods_res)) { foreach($goods_res as $data) { $goods_data['hot'][] = array('goods_id' => $data['goods_id'], 'sort_order' => $data['sort_order']); } } 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 ? $num : $data_count; if ($order_type == 0) { //usort($goods_data[$key], 'goods_sort'); $rand_key = array_slice($goods_data[$key], 0, $num); foreach($rand_key as $key_data) { $type_array[$key][] = $key_data['goods_id']; } } else { $rand_key = array_rand($goods_data[$key], $num); if ($num == 1) { $type_array[$key][] = $goods_data[$key][$rand_key]['goods_id']; } else { foreach($rand_key as $key_data) { $type_array[$key][] = $goods_data[$key][$key_data]['goods_id']; } } } } else { $type_array[$key] = array(); } } } //取出所有符合条件的商品数据,并将结果存入对应的推荐类型数组中 $sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, g.shop_price, ' . "promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img, RAND() AS rnd " . 'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' . " "; $type_merge = array_merge($type_array['new'], $type_array['best'], $type_array['hot']); $type_merge = array_unique($type_merge); $sql .= ' WHERE g.goods_id ' . db_create_in($type_merge); $sql .= ' ORDER BY g.goods_number DESC'; $result = $GLOBALS['db']->getAll($sql); foreach ($result AS $idx => $row) { if ($row['promote_price'] > 0) { $promote_price = bargain_price($row['promote_price'], $row['promote_start_date'], $row['promote_end_date']); $goods[$idx]['promote_price'] = $promote_price > 0 ? price_format($promote_price) : ''; } else { $goods[$idx]['promote_price'] = ''; } $goods[$idx]['id'] = $row['goods_id']; $goods[$idx]['name'] = $row['goods_name']; $goods[$idx]['brief'] = $row['goods_brief']; $goods[$idx]['brand_name'] = isset($goods_data['brand'][$row['goods_id']]) ? $goods_data['brand'][$row['goods_id']] : ''; $goods[$idx]['goods_style_name'] = add_style($row['goods_name'],$row['goods_name_style']); $goods[$idx]['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ? sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name']; $goods[$idx]['short_style_name'] = add_style($goods[$idx]['short_name'],$row['goods_name_style']); $goods[$idx]['market_price'] = price_format($row['market_price']); $goods[$idx]['shop_price'] = price_format($row['shop_price']); $goods[$idx]['thumb'] = get_image_path($row['goods_id'], $row['goods_thumb'], true); $goods[$idx]['goods_img'] = get_image_path($row['goods_id'], $row['goods_img']); $goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']); if (in_array($row['goods_id'], $type_array['best'])) { $type_goods['best'][] = $goods[$idx]; } if (in_array($row['goods_id'], $type_array['new'])) { $type_goods['new'][] = $goods[$idx]; } if (in_array($row['goods_id'], $type_array['hot'])) { $type_goods['hot'][] = $goods[$idx]; } } } return $type_goods[$type]; }
这样改了以后,Bulid的静态文件应该只有13K左右,速度大大加快。
