collecting performance information. The more you collect, the greater the performance loss. There's an interestingThe paradox. To fully monitor performance, you must introduce performance degradation operations into the database. The dilemma that this causes isIs that you cannot be certain that your monitoring behavior has nothing to do with unacceptable performance.Limiting the data retrieved can reduce this uncertainty, but remember that it should

Chapter 1 pointer ConceptA pointer is a special variable. The value stored in it is interpreted as an address in the memory.To understand a pointer, we need to understand the four aspects of the pointer: pointer type, pointer pointingType, pointer value, memory zone pointed to by pointer, and memory zone occupied by pointer. LetWe describe them separately.First, declare several pointers for example:Example 1:(1) int * ptr;(2) char * ptr;(3) int ** ptr;(4) int (* ptr) [3];(5) int * (* ptr) [4];If

software development process is to improve the efficiency of software development, operation and maintenance, and improve the quality of software, customer satisfaction, reliability and maintainability of software. It is not enough to have ideas of all kinds of processes, and we have a series of tools to ensure that these ideas can operate efficiently in practice. A common formula is: Software engineering = development process + tools. Agile Development (development) is a human-centric, iterati

With the continuous development of routing technology, dynamic routing technology is also widely used. Here we mainly introduce the development status and history of dynamic routing technology. The Internet has passed its 40-year-old birthday. Although the media is not surprised by the report, the middle-aged crisis has indeed come, one of them is one of the core technologies that have been advertised and touted as "Dynamic Routing Technology". It is the "key" for the Internet to defend against

layer traffic must be used, that is, the stateful 4 ~ Layer-7 traffic. Separate 4 ~ Layer-7 Traffic testing tools are available on the market, including IXIA IxLoad. One of these tools is to directly connect to the sending and receiving ports of the devices under test, there is no complex and real route table. In order to fully verify the performance of the routing device with the deep packet detection function, the route table and 4 ~ Layer-7 stateful traffic integration testing.The latest dev
