When I test a server, I mainly test three indicators: bandwidth, CPU and hard disk IO performance. Because these three indicators are the three most important factors affecting cloud server concurrency. Bandwidth network, network delay affects the waiting time for users to open web pages, and bandwidth size affects the maximum number of concurrencies that can be tolerated. For example, if a user occupies 1k bandwidth, then 1M can withstand up to about 1,000 concurrencies. CPU performance, CPU performance determines the speed of computing processing. The faster the computing processing speed, the shorter the user's waiting time. More requests can be processed per unit time, resulting in greater concurrency. You may not care about hard disk IO performance, hard disk read and write performance, but if the hard disk reads and writes faster, the shorter the process running time, the shorter the user waiting time, and more requests can be processed per unit time, which brings Greater concurrency.
The test results of this Tencent Cloud network are very good, the bandwidth can be fully charged, and the network delay is also excellent, basically between 20 and 40ms. I know that some small cloud server manufacturers will reduce the bandwidth, because the technical difficulty of bandwidth reduction is simple, just share a bandwidth with several servers, and the benefits can be immediate.

During the test process, I used some test scripts and directly uploaded screenshots of the test results.
Tencent cloud server bandwidth network:
The test results of this Tencent Cloud network are very good, the bandwidth can be fully charged, and the network delay is also excellent, basically between 20 and 40ms. I know that some small Hong Kong cloud server manufacturers will reduce bandwidth, because the technical difficulty of bandwidth reduction is simple, just share a bandwidth with several servers, and the benefits can be immediate.
Tencent cloud server CPU performance:
The CPU configuration is not bad at all. With the Intel Xeon series 4-core 2.6GH CPU, I ran the script and got a score of 2598, which is quite good. If it is a shared cloud server instance, it cannot achieve such a level.
Tencent cloud server hard disk IO performance:
The read and write speed of the hard disk, whether it is small files or large files, is very good and is at the level of SSD hard drives.
