jeecgboot-vue3首次加载时间优化_jeecgboot删除online

jeecg3.6首次加载时间比较长，有时需要十来秒，体验挺不好，需要优化一下。

加载时间长的原因是加载的资源比较大，开发环境下有30多M，生产环境下也有15M左右，这么大的依赖包，加载起来肯定会慢。

知道了为什么加载慢了，优化方法也就有了，那就是去掉不需要的依赖。具体方法如下：

1. 去掉百度统计代码，这个是为了减少不必要的请求

+++ b/index.html

经过上述修改之后，依赖包的体积在开发环境下能减少13M 左右，在生产环境下能减小一半左右。加载速度明显加快。当然，其实还有继续优化的空间，把自己项目中用不到的依赖都删掉就可以。
