In the WLAN Design for optimizing Wi-Fi Video Transmission, we discuss the capacity requirements for wireless video optimization and 802.11n considerations. This article will discuss other network optimization methods for video and methods for measuring the performance of wireless videos in WLAN.
In addition to the basic 802.11n functions used for video optimization, we should also consider using other built-in Priority Methods in network components t

// read the next resultset
reader.NextResult();

You can return multiple objects in a single response to a Web API, and try to combine the multiple objects you return and return to the following:
public class AggregateResult
{
public long MaxId { get; set; }
public List Folders{ get; set; }

With the development of the exchange industry, many new products have emerged. Among them, the Core routing switch is one of them, and it supports high-performance 10-Gigabit interfaces to improve the overall efficiency of the network. Quidway S8500 series 10-Gigabit core route switch is a new generation high-performance 10-Gigabit core route switch developed by
Article Title: Improving Linux system performance to accelerate network applications. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
When developing a socket application, the first task is to ensure reliability and meet specific requirements. With the four tips given in this article, you can design and develop a s
Two ways to improve performance using direct-path insert: direct-pathinsert1. Traditional serial insert
There are two common insert methods:
(1) insert into table_name values (....)
(2) insert into target_table select * from source_table
The above two general plug-ins are inserted in the serial mode by default. The insert data will be written to buffer_cache. check whether there is free space in the block i
caching in your applications, you should consider ways to implement caching at all program levels.
Steve's Caching Tips
Cache as early as possible;
You should implement caching at every level of your application. Add caching support to the data tier, business logic tier, UI, or output layer. Memory is now very cheap-therefore, a great performance improvement can be achieved by implementing caching in the entire application in an intelligent manner.

The following network technologies can greatly improve network performance and security in the context of maintaining lower operating cost growth: number re-positioning technology: The idea of number re-location technology (SNR) is to introduce intelligent number repositioning technol
How much performance can be improved by using the Oracle PipeLined method? Recently, Oracle table functions are used. In particular, the nested table data is returned by the table structure. We found that the PIPELINED method is used, it can indeed greatly improve the performance. Oracle PipeLined, and send it to the next processing stage. Recently, I found a tim

In the early stage of application system development, due to less development database data, the query SQL statement, complex view of the writing of the performance of the SQL statement is not good or bad, but if the application system submitted to the actual application, as the data in the database increases, The response speed of the system is one of the most important problems that the system needs to solve at
Quality is critical for an application to be successful in development. Users are asking them to decide that Android applications installed on their devices respond quickly and with reasonable performance. If the application fails to provide useful functionality and a stable user experience, it will be uninstalled quickly. In this article we will introduce ten tricks to quickly improve Android app developme
1. Use the tostring method of Value Type
When connecting strings, you often use the "+" sign to directly add numbers to strings. This method is simple and can get the correct results. However, because different data types are involved, the numbers must be converted to the reference type through the boxing operation before they can be added to the string. However, the packing operation has a great impact on the performance, because during such processi
' OperationSimilarly, for the ' * ' operation, using the shift operation will be faster and more efficient as int num = a * 4;int num = a * 8; should be changed to int num = a Note:16, 17, the individual does not quite agree with these two articles. This does have better performance, but at the expense of readability. These two operators are not intuitive to many programmers. I think it's a good choice to sacrifice some
I. Indexed views
For years, MicrosoftSQL Server has supported the creation of virtual tables called views. Typically, the main functions of these views are:
Provides a security mechanism that restricts users to a dataset in one or more base tables.
Provides a mechanism that allows developers to customize how users can view data stored in a base table in a logical way.
The capabilities of the SQL Server 2000,sql server view are extended to achieve system

15, open the Apache mod_deflate module, you can improve the browsing speed of the Web page.
16, the database connection should be turned off when use is finished, do not use long connection.
17. Error messages are costly.
18, in the method to increase the local variable, speed is the fastest. Almost as fast as calling a local variable in a function.

The solution is to execute SQL statements directly, and write an extension method on your own. although many people disagree with this method. but I personally prefer to write an extension method myself. in this way, there are two benefits. first, it is easy for developers to use. second, convenient management. some netizens have suggested using ObjectStateManager. changeObjectState is used for batch dele
