How to test a CVM? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Now, many enterprises and webmasters have begun to choose CVM to build a station, and many merchants also support trial before purchasing CVM. So when we try it, how should we test it?

Several main aspects of testing a CVM

1. Test CPU, test its computing power, the shorter the running time, the better.

two。 Test memory, test memory allocation transfer speed. The greater the memory throughput, the better

3. Test the disk, the greater the disk throughput, the better the disk performance. The shorter the time, the least latency for disk io.

4. Test the bandwidth and test the performance of private network bandwidth between CVMs. The greater the bandwidth throughput, the better the bandwidth performance.

A simple method for testing CVM bandwidth

The bandwidth is a very virtual thing, it is not like the hard disk size, memory size that can be directly seen. Downloading files is a simple and effective way to test bandwidth.

1. Download a few tens of megabytes of compressed file on the cloud server and put it in the root directory of the website.

two。 You can download the files you just put in the CVM on your own computer using an IE browser or with other download tools.

Downloading files directly from an IE browser is the recommended method, as other download tools may be speed-limited and inaccurate. The "transfer speed" can be seen directly when the IE browser downloads the file. The calculation method is 1m bandwidth = 1024kb/s=126KB/s.

The response speed of the CVM is different from the bandwidth (download speed). The response speed is mainly to test the performance of the CVM. Testing the response speed of a CVM requires the help of specific tools.
