In Cucumbertown, we use a variety of methods to ensure that the loading time of our pages is within 2 seconds, not more than 3 seconds. we really value this.

If the response exceeds 3 seconds, we will receive many alarms.

A few days ago, Chris Zacharia did not write an article about the importance of page weight and the countermeasures of YouTube. At that time, it would take more than 20 seconds to load the page with an alert from Google Analytics in the inbox. then you can let go of everything and see what happened.

Generally, the loading delay of webpages is discovered after a random test of product promotion or a large amount of use. But this happens and the alarm is a day later than expected. This is indeed surprising. In IMO, the unknown issues that you have not found the root cause are far more dangerous than those that you have recognized.

We started a detailed investigation and saw the result:

Connecting these with other results makes everything clear. Cucumbertown is a food channel in Nigeria and a quality blog in Thailand, making it popular in different regions. But as you can see, page loading times in these countries are not normal.

Cucumbertown is an asset-heavy website. although we have postponed all operations on requieJS and actively loaded JavaScript as needed, we have made a lot of investment in loading basic scripts.

We have confirmed that Cucumbertown's loading time in the United States is 2.5 seconds. compared with other countries, this is simply the speed of light, and the DSL device has a one-week delay of 43 milliseconds around the world. Therefore, it is time to consider the advantages of CDN 'ing.

We first used Akamai at Zynga, but then we switched to LimeLight because they seem more trustworthy. However, the recent CloudFlare activity on HackerNews and their umbrella features seem to be an attempt to explore. So I learned about and tested CloudFlare.

It is a good thing to have a lot of demands, but if the web page cannot be opened all the time, it will be the same as the cache gets evicted. If it is the first time a webpage is clicked after it is inactive, the webpage loading will become slower. However, the webpage loading time required for subsequent follow-up is between 1.5 and 2 seconds.

I used to think that CDN is a very expensive word for enterprises. But now the situation is: the beginning of a global service, and it seems to be indispensable.

Finally, what is your experience, and what do you think?
