How to slow the CVM configuration website? 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.

What if I configure a slow website card on a CVM? There are many reasons why the website access card is slow. A complete HTTP request includes domain name resolution, establishing a TCP connection, initiating a request, the CVM receives the request and returns the processing result, the browser parses the HTML code and requests other resources, and renders the page.

Among them, the request process of HTTP goes through the user's local client, the network node between the client and the access server, and the server. In these three links, problems in any one of the links may lead to slow access to the website.

Check the local client

The local client accesses the network diagnostic analysis system to test the speed of local access to each domain name. Based on the test results, confirm whether there is a problem with the local network.

Check the network link

Local client ping CVM public network IP to confirm whether there is packet loss or high delay. Use the dig/nslookup command to check the parsing of DNS to see if there are any problems caused by DNS parsing. You can also directly use the public network IP to visit the corresponding page to find out whether the access is slow due to DNS problems.

Check server usage

If the CPU/ memory usage of the CVM is too high, or the bandwidth usage is too high, determine whether the resource consumption caused by the server load is increased. If the CPU or memory utilization is too high, it is easy to cause problems such as slow service response and failure to log in to the server.

If it is due to too much website traffic or resources, it is recommended to optimize the business program or upgrade the server configuration. You can also share the pressure on existing servers by buying new servers.
