Recently, because the system load of the website is often too high, I checked the reason is that after enabling SWAP due to memory exhaustion, the disk IOWait appears to be high. In my impression, the hard drive of a classic VPS host is an SSD, and the read and write speeds previously tested were as high as GB/s or above. In theory, such a good hard drive is very good for building a website. However, when I tested several classic VPS hosts I was using again, I found that the performance and speed of the classic VPS hosts were much lower than the previous test data. This can be seen from one aspect that the classic VPS hosts are the same The hen's chicks began to increase a lot, which indirectly led to a decline in the performance of the VPS host and a much lower cost performance. This article will share the before and after comparison of the performance and speed of classic VPS hosts. In addition, the price seems to be "rising" year by year. The recent cancellation of the OpenVZ package has made many users "uncomfortable". Generally speaking, the price of VPS hosts is getting more and more expensive, and the cost-effectiveness of VPS hosts is constantly decreasing. Please be careful before choosing. For more reviews on the use of VPS hosts, you can view the special topic: VPS host ranking list. If you want to pursue a VPS with high IO, it is best to choose SSD. Here are:

1. Classic VPS host price increases
Here we take the currently very popular CN2 GIA VPS as an example. The previous price was about ten dollars per month.
Now the price of the same package has "silently" increased to US$18/month, which is almost the same price as the VPS host of South Korea's Kdatacenter.
Currently, the best and most expensive ones are the CN2 GIA ECOMMERCE plan and the CN2 GIA regular plan, followed by the HONG KONG plan, and finally the CN2 regular plan and the KVM regular plan. The prices of different VPS packages vary greatly, so please choose based on actual conditions. choose.

2. Classic VPS host disk IO decreases
The previous hard disk IO read and write of CN2 GIA VPS was basically between 800-900MB/s.
Now, the disk IO read and write of the same VPS host I own is only about 200MB/s. This speed is really comparable to Alibaba Cloud and Tencent Cloud.
3. Classic VPS host bandwidth decreases
The decrease in bandwidth mentioned here refers to the decrease in shared bandwidth. It should be because there are too many users and fewer resources are shared. The bandwidth tested in the past can reach about 600MB/s.
The current bandwidth test data is around 300MB/s, and the shared bandwidth has dropped by half.
The VPS host performance and speed test methods used in this article are referenced from: Three free tools to help you detect the authenticity of the VPS server - VPS host performance and speed test methods.
4. Summary
Some students who have purchased classic VPS hosts can compare with my test data. CN2 GIA VPS reference: CN2 GIA VPS performance and speed, Hong Kong computer room reference: Hong Kong computer room VPS performance and speed, ordinary line "classic" VPS hosting performance and speed.
When using a classic VPS host, you need to pay attention to lags at night. American VPS hosts generally have normal access during the day, but problems are prone to occur at night. In particular, CN2 GT is obviously less stable than CN2 GIA. The picture below is CN2 GIA monitoring chart.
The picture shows that the ping value of the classic CN2 VPS GIA remains around 200 during the day, but rises to around 250 at night. This is a very interesting pattern.
