月光下的足球 1月前3楼代码方式楼上已经很全了！如果你的数据量越来越多，那么推荐 WordPress 优化的另一种方法：缓存。这样别人访问页面的时候，可以直接提供缓存页面和数据，减少了运行站点所需的服务器资源占用，大大提升网站的运行速度。我这里推荐几款经典热门的缓存插件：
W3 Total Cache（老牌免费缓存插件）
WP Rocket (非常棒的收费缓存插件，WordPress大学目前用的)
WP Fastest Cache （值得推荐）
LiteSpeed Cache （值得推荐）
WP Super Cache （老牌免费缓存插件， 建议配合 Autoptimize 一起用 ）
如果是VPS或云服务器（内存1G以上），也建议使用 Opcache 和 Memcached 服务器端缓存，性能更佳！
