According to the content of the PPT, I used Yslow to check my homepage, only to get an "F 47" (frankly, very discrepancy with my estimate).

The main problem is that Gzip compression is not turned on, and HTTP header caching is not set. Seems to have been tossing for so long, in addition to server-side performance, the client's cache can not be ignored.

Think about it, if Taobao home is not cached, even if it is more than 1KB of page capacity, multiplied by billions of PV per day, this number will be how huge.

Finally, provide a PPT download for this session and thank them again.
