Discussion on the experience of Lanmang Technology CDN's accelerated trial

Our web SITE Intelligence recruitment www.http://www.aliyun.com/zixun/aggregation/37853.html ">zhaopin.hk because of the current northern users and the Shanghai area users more, Our server is in Dongguan Telecom room, there are many customers respond that the site is slow.

So hold the attitude to try to find the domestic more well-known CDN supplier Xiamen Lanmang www.lanmang.com do a CDN test.

Site on September 23 9 o'clock to start testing until September 24 14 o'clock test completed, or found a lot of problems. Originally decided to test three days, found the following problems, the company decided to terminate the test in advance.

1. The flow of the site is true and accurate, because according to their flow chart shows that 15 o'clock in the afternoon traffic is particularly large, but from the CNZZ statistics, there is no obvious change.

2. The synchronization of the website, there is a customer post after the post, login can not find a position, but we are in the background and the front desk are able to clearly see the position information. It was normal to post a post after it was deleted.

3. Cannot resolve pan domain name.

4. Whether there is a real acceleration effect. Find a lot of friends and customers have tested, only one Unicom customer said faster than before, a lot of local customers from the original 10ms to 20ms, almost a delay of one times.

5. Whether the price is too high, currently in the Chinese market to do CDN acceleration of a few companies, the price is relatively not very transparent. Lanmang There are two ways to charge, by flow or by bandwidth. According to the results of the day's test 3g daily flow, we need to spend 3g*30 days per month * 50 Yuan/g=4500 yuan, or the choice of bandwidth charges 400 yuan/M, according to the 5M flow calculation, monthly also need to spend 2000 yuan. And our average daily traffic is about 10G, accelerated the day, the site only 6G traffic plus acceleration of 3G basically belong to the normal state.

But after spending so much each month, it doesn't speed up much.

Lanmang CDN Quotes:

1 1g-100g 2 to 50/g 1. Provide user flow monitoring system

2 100g-500g 5 to 40/g 2. Provide customers with real-time self-service CDN

3 500g-1000g 30/g 3. Provide users with CDN self-service renewal system

4 1000g-5000g 20/g 4. According to the actual use of traffic charges, fair and reasonable

5 5000G 20/g 5. Unlimited time, price for one-time purchase flow price

Combined with the above factors, we feel that CDN technology needs to be improved, and the charges are still to be adjusted. The current dual-line IP occupancy market is relatively large, or based on the current CDN market immature. The biggest benefit is to prevent the server from being attacked and to protect the source server.
