试用Google牌CDN: Google PageSpeed Service

Google

Update: Google 2015年8月3日要关闭这个免费服务了,以下是公告原文:

On July 28, 2011 we announced PageSpeed Service, an online service to automatically speed up web pages. In the last 4½ years, PSS has delivered millions of pages for thousands of sites, all for free. While a number of sites continue to enjoy the benefits of PageSpeed Service, we see much broader adoption of PageSpeed technology through our open-source products and have therefore decided to focus our efforts on improving those.

Today we are announcing that PageSpeed Service will be turned off on 3rd August 2015. Users must change their DNS to point away from the service by this time, or their sites will cease to function. We have created a migration page that includes assistance for changing DNS as well as information on other ways PageSpeed technology can be employed on websites. Please see https://developers.google.com/speed/pagespeed/service/Deprecation.

At the same time we are also announcing the deprecation of PageSpeed integration with Google App Engine. If you are using PageSpeed integration on Google App Engine, it will continue to function until 1st December 2015, after which PageSpeed optimizations will no-longer be applied to your app. No action is required on the part of App Engine users; after this date apps will continue to operate, except without the benefit of the PageSpeed optimisations. Users that wish to pre-emptively disable PageSpeed can follow the instructions at https://cloud.google.com/appengine/docs/adminconsole/pagespeed#disabling-pagespeed.

The open source PageSpeed server modules mod_pagespeed and ngx_pagespeed and the PageSpeed Optimization Libraries are unaffected by this announcement and development on these will continue.

The PageSpeed team.

Google公司在全世界有很多的数据中心和服务器,我曾经想,要是Google提供它的资源为我们的普通网站加速,那就太厉害了。没想到,Google还真早在2011年就提供这样的服务,叫作Google PageSpeed Service,目前依然免费。

我去Google PageSpeed Service网站用我的英文网站申请开通了账户,不到几个小时就收到了回复,申请通过。简单设置几下以后,网站就开始经由Google的全球网络加速,极速体验且免费不限流量,还支持HTTPS SSL。

我的英文网站搭建在戈戈主机上,由于位置在美国,所以想利用Google PageSpeed Service加速美国以外的网站速度。现在用上Google PageSpeed Service,网站在全世界都有着相当于Google搜索的速度(中国大陆和朝鲜除外)。

和普通的CDN有些不一样,Google PageSpeed Service利用它的全球数据中心为网站加速之前,还会对网页内容重新编写、压缩合并CSS, JavaScript和图片,并且使用SPDY协议分发从而减少网页请求数,进一步提高网站的传输速度。完全可以理解为免费的Google牌高级CDN服务。唯一的缺点是不支持裸域名(即不能是 tumutanzi.com 形式)。

很奇怪,Google于2011年就开启了Google PageSpeed Service服务,到现在还没有进入到大规模使用。虽然官方声称将来有收费计划,不过我估计,就算收费也可能会有免费的产品。

Google PageSpeed Service目前在国内还属于可用状态,也许是由于Google在中国大陆的状态,使得国内众多网站主不敢使用Google PageSpeed Service加速网站,谁也说不准什么时候Google PageSpeed Service就被墙了。
