This article will explain in detail how to optimize the CVM. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

When we use CVM, we all want to make some performance optimization to get the best access effect. Here are several ways to optimize the CVM.

Use a SSD hard drive

In addition to memory optimization, you can also optimize this side of the disk. Compared with the traditional mechanical hard disk, solid-state hard disk has the characteristics of fast reading and writing, light weight, low energy consumption and small size. However, the price of ssd is more expensive than that of traditional mechanical hard drives, and ssd can be used to replace mechanical hard drives under certain conditions.

Using an in-memory database

An in-memory database is a database that manipulates data directly in memory. The data read and write speed of memory is several orders of magnitude higher than that of disk. The in-memory database leased by the server has redesigned the architecture based on all the data, and has made corresponding improvements in data cache, fast algorithm and parallel operation, so the data processing speed is much faster than that of the traditional database.

Increase internal cache

Many web applications have a lot of static content, which is mainly small files and will be read frequently, using Apache and nginx as web servers. If the load is large, we can build a cache server at the front end to cache the static resource files in the CVM into the operating system memory for direct read operation, so as to reduce the time consumption caused by accessing the disk.

Optimize the database

Most of the server requests eventually fall into the database, and with the increase of the amount of data, the access speed of the database will become slower and slower. Dividing the database into tables according to the appropriate business rules can effectively improve the access speed of the database and improve the overall performance of the server. In addition, for business query requests, the index can be set up according to the relevant requirements when building the table to improve the query speed.

This is the end of how to optimize the CVM. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
