sum up, software performance testing is the implementation, monitoring-〉 analysis-〉 The process of continuous tuning, that is, monitoring is to provide more reference data for analysis, the analysis is for tuning, tuning is to solve the current system performance bottleneck
The network structure is complex and changeable. All kinds of network protocols are difficult to grasp, let alone applications. Here we can use the network protocol analysis software for management. Some people often ask why I can only see my own communication? Why can't I see the Communication Status of XX? Is it software limitations? In fact, this kind of probl
Requirement analysis is the first stage of software development, and it is a key step to the success of software development. The task of the requirement analysis is to understand that the system must complete the work, and the following is a brief summary of the requirements analy

Requirement Analysis of write software
Demand always answers the question of "what is needed", and implementation always solves the question of how to achieve it. The requirement is to achieve the goal, that is, to determine the path and method to reach the destination in advance. To avoid going astray, we must avoid misleading requirements analysis errors.First,
development, and 20%-35% of the total workload of testing. The proportional evaluation method is the workload allocation based on the full life cycle model of software. This is a quantitative result from the summary and analysis of a large amount of historical data.
Estimate the test workload based on the Development workload is relatively accurate. This method

. The second interface is the programming interface, in Tachyon there are two main interfaces for user programs, one is Tachyonfs, which is the most basic programming interface provided by Tachyon, which covers all the functions Tachyon provides to the user program, including such as Delete, mkdir, rename and so on, through the basic functions of programming, you can achieve the operation of the file system. The other is Tachyonfile, which provides so
limitations, database access performance settings, etc. often become a constraint on software performance, but these factors are obviously not the user's most concern, we need to pass a number of settings before testing to minimize the impact of these factors.
In addition, the user is more concerned about which part of the system performance situation will also affect the scope of work. If the link is a new system, and some of the link is already a m

In the final analysis, the overall protection products focus more on matching and integrating with existing information systems and management systems, and document encryption products focus more on the impact and changes on operator habi
