07:41 Announce: Front End Performance Optimization » MySQL Performance Blog

I guess many of you know us and so our company for MySQL related services. It is true this is majority of our business at this point but it is far from everything.

Our goal in reality is to help people to build and operate quality systems, typically web sites, which means we help customers with performance, scalability, high availability as the whole, not just MySQL related issues.

Indeed if you look at MySQL driven web site its properties will likely depend on a lot of factors - good web side configuration, which is about caching, proxying, using multiple data centers or CDN, serving static content reliably and efficiently. Then it comes to efficient web application architecture and code - being scalable, efficient, highly available, secure and fault tolerant. Caching in particular as memcache plays important role here besides MySQL though quite typical you also would see external queue, message parsing, search systems etc being important components besides MySQL.

MySQL is important component but just a component, though due to its complexity it is often where
professional help is looked for dealing with scaling and high availability.

Even more. Everything what we’ve described is only part of the problem. It is all about generating dynamic content quickly or serving static files which is only one side of the problem. The other side is making things fast from the client prospective where our new service - front end performance optimization comes to play.

We look to reduce number of requests and transfer size. Browser and HTTP Caching (Request not made is far better than even fastest serviced request), making content download as parallel as possible and making page to start render as soon as possible.

Front End performance optimization is often needed to change your site from good to great. Market leaders such as Google tend to do it a lot and it is well known fast loading web pages improve user experience and make people to stay on site longer and return more likely which in the end improves business goals such as showing advertisements, product downloads or purchases.

Some people make a mistake by thinking their site are already great by looking at their web site from location which is close to the data center. This gives huge available bandwidth with pretty much no packet loss as well as very low latency.

Most likely these conditions are not the case for all of your users and customers - some may be accessing the system from remote location with high latency and packet loss. Others may be accessing it via crowded public wireless connections and there is class of mobile users with less than perfect latency and download speeds a lot slower than home/office broadband.

This especially comes as important issue to me personally then I’m traveling or using mobile Internet for other reasons - so many web sites become so painfully slow they are barely usable even though their backend does not perform any slower in this case.

By adding front end optimization services we are able to help to deliver great performing web sites whatever performance limiting factors are.

P.S As this is the new service we’re looking for feedback on how to make it better. If you’re interested in your site evaluation and would be willing to provide us feedback about recommendations and general service delivery, drop us a note and we’ll pick couple of sites to review free of charge.

21:58 SNS小结+问题 » laolu's blog: Blog

前几天连续写了多个关于SNS的帖子,现小结+问题:

  • 使用
    这两年SNS不是趋热,而是陡然火热(见调查数据——只有每天使用SNS的比例大幅上升,其他都没增加)。从这个角度说,SNS就像email那样,似乎不算很过分。
  • 收入
    SNS的广告收入并不高,到2012年为26.1亿美元,占网络广告的比例最高也仅6%(美国的数据,一家之言)。这与搜索广告占网络广告的比例,从02年的15%到03年的35%、04年的40%,相差较大。仅仅凭这点业绩,要维持SNS的长期开心,恐怕比较难。从这个角度说,SNS就像email那样,似乎也不算过分。
  • 发展
    • 1 商业价值?这是经济基础。
    • 2 扩展和开放?这是方向问题。
      • 2.1 SNS中的社交图,比现实生活中真实的社交关系要简单,对用户和营销者来说也许都需要扩展。或者,借助SNS来研究人类社交关系的发展,有没有营销切入的可能?
      • 2.2 SNS走向开放,支持类似OpenID(英文中文)的统一身份,个人数据可携带,那用户的活动信息就可能会脱离具体的SNS网站,哪方将得益?
      • 2.3 SNS能否用来推进其他互联网业务的发展?Google、Yahoo!、Microsoft这三大互联网巨头,在单独运营SNS上迄今都表现不佳,但它们申请的一些专利,却很发散、很有启发。它们的搜索和门户业务,也许能成为再次进入SNS的基础,形式上也许是融合和结合。比如:把SNS的用户活动信息与搜索融合起来,可以极大地提高对用户搜索意图的把握;或者,把门户的广告主和广告发布系统,与SNS的用户兴趣结合起来。
      • 2.4 垂直SNS、企业/商业SNS、SNS+X或X+SNS(X为其他互联网业务)是否会有所发展(参见“洪波:SNS无泡沫 会诞生垂直SNS平台”)?

获得市场,仍然需要技术创新。

今天顺便把写这个幻灯片时看的参考书目整理出来,做了一个豆列

1: 荣格性格哲学
2: 职业的有效管理
3: 长尾理论
4: 战略管理(第六版)
5: 知识管理的现在与未来
6: 知识管理

豆列的地址在这里:http://www.douban.com/doulist/182022/

很希望豆列可以Embed出来放在blog里,就像这个幻灯片一样。为何豆瓣不做一个豆列播放器呢?不过看起来,开发一个日记功能和图片功能比豆列播放器更具战略意义。希望豆瓣的团队多招些人,把一些现有的功能继续提升改良。

整理这个豆列时,也看到自己早些年在很多书的评论页都留下了脚印,算是回顾一下自己的读书历程。

如果你看了《善用网络,因人而异》幻灯片,可以继续看这个豆列,挑选你喜欢的话题看看书评或者买书来看。
