Discussion on improving the performance scheme of server system

Server | Performance with the development of business and the depth of information, the scale of enterprises has been expanding, the application has been increasing. The original system after a period of time, it is difficult to meet the demand, therefore, enterprises need to transform the original information system. In the process of upgrading, the server system that is the core of enterprise information system is the first, because almost all kinds of applications run on the server system. How to improve the performance of the server system is the concern of enterprise information management personnel.

There are a number of ways to improve server system performance, one is to completely replace the server, and one is to continue to retain the original server, just replace parts. In addition, in order to improve the reliability of the server system, cluster technology can be used. In order to improve the efficiency of server system, load Balancing server and Web caching server can be increased. In order to ensure the security of the system, can increase the VPN and firewall and other secure servers.

Reporters and a number of users, professional manufacturers on this issue has been discussed. The reasons for improving the performance of the server system are various, and the application is the key. Most organizations upgrade the server system because they want to run a new application system. For example, an enterprise needs to have an ERP system, so the computing power and resources requirements are very high. In particular, storage resources, the past server system can not meet the requirements, at this time, must replace the original system.

For the original system, run some server detection program, you can get the server system specific operation, to determine whether the server system needs transformation is very advantageous. The following items are mainly examined.

1. Processor utilization

This metric represents the impact of running applications on processor efficiency. If the utilization exceeds 50% for more than one or two minutes in a row, it indicates that the system needs to improve performance.

2. Total capacity of high-speed buffer zone

The lower the indicator, the slower the file is executed, and the more memory should be added if the indicated number is less than half the number of buffers.

3. Current number of service processes

The number of processes indicates the number of read requests. A service process is established when a read request appears and no corresponding process responds immediately to processing. The buffer is too little to make the indicator rise. With a lot of memory, the number of service processes is still rising, which requires a disk channel to help. Upgrade the controller or disk, or move the high load application to another server.

4. Packet Receive buffer number

To save the packets from the workstation until they are processed by the server. Allocate buffers as needed, and the number increases to indicate that server performance is not sufficient to take on so much load.

5. Cache Hit Ratio

If the long-term buffer hit rate index stays above 90%, the server gets a good file system configuration.

As each enterprise is different, the way to improve the performance of the server system varies. Below, according to the general small and medium-sized applications, key applications and Web site applications and other specific circumstances, to improve the performance of the server System practices and solutions.
