Hexo-Next提高加载速度

Hexo作为纯静态博客最大的优点就是快，但要真正的快起来你可能需要做这些事情。

CDN加速

这里只是针对第三方静态文件的加速，修改Next主题配置文件_config.yml如下：

# Be aware that you would better use the same version as internal ones to avoid potential problems.
# Remember to use the https protocol of CDN files when you enable https on your site.

图片懒加载

文字先出来，图片再慢慢出来，可以显著提高体验。

安装插件 npm install hexo-lazyload-image --save

修改项目配置文件_config.yml:

# 图片懒加载
lazyload:
  enable: true 
  onlypost: false
  loadingImg: /images/loading/loading.gif #如果不填写图片则使用默认的图片

 精简功能

功能涉及多个请求时会比较明显得拖慢加载速度，例如不蒜子、DaoVice，要考量这些功能是否真(hua)的(er)需(bu)要(shi)。（像我已经关掉了DaoVice 和 看板娘）
