使用gulp插件

var gulp = require('gulp');
var minifycss = require('gulp-minify-css');
var uglify = require('gulp-uglify');
var htmlmin = require('gulp-htmlmin');
var htmlclean = require('gulp-htmlclean');
// 压缩 public 目录 css
gulp.task('minify-css', function() {
    return gulp.src('./public/**/*.css')
        .pipe(minifycss())
        .pipe(gulp.dest('./public'));
});
// 压缩 public 目录 html
gulp.task('minify-html', function() {
  return gulp.src('./public/**/*.html')
    .pipe(htmlclean())
    .pipe(htmlmin({
         removeComments: true,
         minifyJS: true,
         minifyCSS: true,
         minifyURLs: true,
    }))
    .pipe(gulp.dest('./public'))
});
// 压缩 public/js 目录 js
gulp.task('minify-js', function() {
    return gulp.src('./public/**/*.js')
        .pipe(uglify())
        .pipe(gulp.dest('./public'));
});
// 执行 gulp 命令时执行的任务
gulp.task('default', [
    'minify-html','minify-css','minify-js'
]);

执行压缩

hexo clean && hexo g gulp && hexo d

nginx缓存

    gzip_buffers 16 8k;
    gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

使用cdn加速

深度优化

waterfall
看自己那部分比较加载时间比较长的可以相应优化

最后可以把github上相关内容使用国内的做加速，以及自己可以搞cdn加速整个网站，有的cdn可以免费443端口，有的只有80端口，免费的好几个要备案，又是身份证信息，懒得搞

期间还发现一个问题，就是百度的推送错误(百度推送用了400ms，mmp)
