According to the tradition, parameters and settings of different Linux distributions and kernels have been changed, so that the system can achieve better performance. The following section describes how to use the following techniques to optimize performance in Red Hat Enterprise Linux AS and suse linux Enterprise Server systems: QUOTE: 1. Disabling daemons (disa
not only hard disk operations, but also tty and inter-process communication. In a sense, the file system is at the core of the entire operating system. Because the user program itself is just a file. To find out the file system,

At a higher level, this means that the machine needs to perform less work than it can handle. Note: If the uptime command on a dual-CPU machine displays a load average of less than 2.00, this indicates that the processor still has an additiona
must meet application performance, but these channels may not be able to provide sufficient surplus to meet the needs of many high-bandwidth networks in the future. In order to compare and verify that the six types of cabling solutions provide better transmission quality and faster network speeds than the recently released 5e standards, recently, the American lab conducted a channel surplus experiment using three high-speed, high-density information
The database SQLServer is born with the same parent in the Windows operating system, and they have technical connectivity. This is reflected in many aspects. For example, in our daily work, we can adjust some parameters of the Windows operating system to improve the performance of the SQL Server database server. I. restrict the size of User

performance, use the option in Listing 2.So far, readers with security awareness should feel vigilant. Security is always a trade-off between functionality and risks. In our example, the functionality is speed, and the risk is to allow unauthorized access to files on the system. One of the measures to mitigate the risk is that the lamp application server typically focuses on a specific function, and users
Linux provides a very good file Virtual System (/proc) to monitor system performance. The/proc file virtual system is a mechanism used by the kernel and kernel module to send information to processes. It exists in the memory inste
boundaries between the user space application and the kernel. In addition, before entering the kernel, your call will pass C library to enter a common function (system_call () in the kernel ()). Slave In system_call (), this call enters the file system layer, where the kernel will determine which type of device is being processed. Finally, the call enters the socket Layer, where data is read or queue
AbstractWhether the application logic design of the client/server is reasonable directly affects the processing performance of the Client/Server application system. This article uses the oracle 7 server as the platform to propose some methods to determine how to divide the application logic, so that the client/server application system has a high processing ef
size subscription Queue_depth parameter size In the AIX environment, setting the queue depth (queue_depth) of the fastt Logical Disk is very important to system performance. For large fastt configurations, many volumes are connected to the host. This setting is more critical for high reliability. The queue depth

Why do you want performance tuning? Most Linux distributions are designed to be fully compatible with most computers in the marketplace. This is a fairly mixed set of hardware (hard drive, video card, NIC, etc.). So Red Hat, Suse,mandriva and some other distribution vendors have chosen some conservative settings to make sure the installation is successful.Simply put: Your distribution is running well, but it can work better!For example, there may be

For your instance of SQL Server, if you enable Instant file initialization, you will get a huge performance boost under certain circumstances. Instant file initialization defines how the SQL Serve
