memory usage is smooth. So, this value is the performance of the system.Four, find the limit value of the system. For example: In the case of a success rate of 100% (regardless of the length of response time), the system can adhere to 10 minutes of throughput.Five, do burst Test. The throughput performed in the second step is executed for 5 minutes, then the lim

for the convenience of discussion. Object-oriented systems integrate data and code together through "objects," rather than seeing programs as composed of detached data and code. An object is an abstraction of a data type that has state (data) and Behavior (code) Object-oriented includes inheritance, polymorphism, virtual derivation, and so on, we will look at how the Go language handles objects,
