寻找关于“做 X 需要多少时间”的 Google 帖子
我记得读过谷歌某人的一篇文章，其中包含一些大概的统计数据，例如需要多长时间：
- 获取锁
- 从寄存器、内存、磁盘、远程磁盘读取/写入一段数据
- 获取页面
- ...
（Don不明白我的确切统计数据）。你能帮我找到这个帖子吗？
I remember reading a post by someone at Google with several ballpark statistics such as how much time does it take to:
- Obtain a lock
- Read/write a piece of data from registers, memory, disk, remote disk
- Fetch a page
- ...
(Don't catch me on the exact statistics). Can you help me find this post?

His latest post on John Rauser (Amazon)'s presentation at Velocity 2010 may be of interest to you.
Edit: You'll also be able to find on his site a power point presentation on front-end optimization which is pretty interesting and has a lot of tips on how to make your site load (or appear to load) faster.
这不是我想要的原始文章，而是 本文确实给出了其中几个操作的数量级。
This was not the original article that I had in mind, but this article does give order of magnitudes for several of these operations.
