Analysis: How to run test cases in multiple threads
unittest First of all, it should be noted that unittest itself does not support multi-threading. Of course, if you have learned Python’s threading module, it may not be impossible. However, I searched for a long time on stackoverflow. Most of them introduced the unittest Test multi-thread module, not how unittest itself runs multi-threaded use cases. […]

13 Case Studies | How does TCP congestion control cause business performance jitter?
This lesson will share with you the relationship between TCP congestion control and business performance jitter. TCP congestion control is the core of the TCP protocol and is a very complex process. If you don’t understand TCP congestion control, you don’t understand the TCP protocol. The purpose of this lesson is to introduce some pitfalls […]
18 Case Studies | Does business need to use transparent pages: Water can carry a boat, but it can also capsize it?
The case of this lesson comes from a stability problem that helped the business team analyze many years ago. At that time, the business team reported that the CPU utilization of some of their servers would soar abnormally, and then recover quickly, and the duration was not long, about a few seconds to a few […]
08 Case | Shmem: The process does not consume memory, where does the memory go?
In the previous lesson, we talked about the leakage of process heap memory and the harm of OOM caused by memory leaks. In this lesson, we will continue to talk about other types of memory leaks, so that when you find that the system memory is getting less and less, you can think of what […]
JAVA Deepening Chapter_37 – TCP Communication Implementation and Project Cases
TCP communication implementation and project cases TCP communication implementation principle We mentioned that the TCP protocol is connection-oriented, and the client and server must establish a connection during communication. In network communication, the program that actively initiates communication for the first time is called the client program, or client for short, and the program that […]
