WordPress网站卡顿加载慢的原因：
众所周知WordPress建站系统服务器是在国外，当用户在国内访问国外的资源时，访问页面速度必然会下降很多，比如谷歌字体，后台系统自带的图片、缓存、API、等等之类因素都会影响页面加载速度。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/30776.html
解决办法一、（使用代码实现加速）
复制下面禁用谷歌字体代码放入到主题文件下的functions.php下面，注意是需要放在<?php 代码下面（修改之前建议先备份文件，以免发生意外的错误。）文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/30776.html
// 屏蔽谷歌字体
add_filter( 'gettext_with_context'<span%20class="enlighter-text">, 'wpjam_disable_google_fonts'<span%20class="enlighter-text">, 888, 4);function wpjam_disable_google_fonts($translations, $text, $context, $domain ) {$google_fonts_contexts = array('Open Sans font: on or off'<span%20class="enlighter-text">,'Lato font: on or off'<span%20class="enlighter-text">,'Source Sans Pro font: on or off'<span%20class="enlighter-text">,'Bitter font: on or off'<span%20class="enlighter-g1">);if( $text == 'on' && in_array($context, $google_fonts_contexts ) ){$translations = 'off'<span%20class="enlighter-text">;}return $translations;}
// 禁止古腾堡加载 Google 字体
add_action('admin_print_styles'<span%20class="enlighter-text">, function(){wp_deregister_style('wp-editor-font'<span%20class="enlighter-g1">);wp_register_style('wp-editor-font'<span%20class="enlighter-text">, ''<span%20class="enlighter-g1">);});
下面是其他一些禁用加载的代码，根据个人需求选择性使用，每个代码之前都有备注含义，同样是放入到主题文件下的functions.php下面文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/30776.html

解决办法二、（如果不会代码的情况，利用WPJAM BASIC插件实现加速）
1.后台插件库中搜索:WPJAM BASIC 并且安装。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/30776.html
