time. For example, the system throughput is 10 per second for systems that require a user to log on for 1 seconds, and if the system supports 10 simultaneous users and the response time is 1 seconds.3. Performance counting The Crying device describes some data metrics for server or operating system performance. For example, for Windows systems, the amount of memory used, process time, CPU occupancy, and so on.We as testers, of course, care about software performance testing to give users good a

in the same way, then add the read version number to the condition of the UPDATE statement, for example, the version number that is read is 1, The statement that we modify the data can be written like this, update the Set field of a table = a where id= and version=1. So if the update fails, it means that there are other transactions already modified in the concurrency situation, then the system needs to throw an error to the client. Allow the client to process itself and the client can choose t

at all times. Based on this statistic, you'll see which upgrades are selling better and are more popular with players. Further down, you can also find out if a user is only involved in a certain type of micro-transaction and make adjustments (if necessary) to the game based on this.Finally, I hope the above list of indicators will help game developers to better study game performance. Keep in mind that specific indicators may only be available for specific games, and you need to select the corr

connected to two neatly arranged icons, the line is drawn as a series of segments connected at right angles. This format is the most commonly used in this book. With care, the most line crossings can avoided. If a line crossing is necessary and there was ambiguity about what the paths is connected, a small arc can used to Indic Ate a line crossing.Note that most of the lines can be avoided by crossing. If a crossover line is unavoidable, there is ambiguity as to how the path is connected. A sma

This article describes some of the basic and most important terms of Docker: Image: Mirroring is the cornerstone of building the Docker world, where users create containers based on images, a layered structure based on a federated file system, built by a series of instructions. It is easy to understand that mirroring is the program code that a container runs. Registry: Docker uses Registry to save user-built images. Registry is divided into public and private two kinds. The public regis

This is a very popular way to explain the sentence briefly.Within a custom class, if you customize a plus "+" method.So in other places the header file can be used directly, without instantiating it, just by importing the header file of the class that contains the plus "+" method.For example, the direct use of the formula should be able to understand, a pile of words to explain more and more ignorant, simple formula:　　　　　　[The Plus "+" method where the class name in the class is the plus "+" met

subscript starts at 0--the subscript of the first element of the array is 0. The subscript of the last element is the array length minus 1. The subscript operation returns an Lvalue, which can be used as the left operand of an assignment operation, equivalent to assigning a new value to the element referenced by the subscript. Operator ( operator)The fetch address operator requires an operand whose only operand must be an Lvalue object, which returns the storage address of the operand object in

Vi. Sound Card terminology 　　 DSP: digital signal processing (Digital Signal Processing ). DSP technology is widely used in analog electronics, such as Tone Control, distortion effect generator, and wah-wah pedal. At the same time, the DSP can also be used in a variety of effects, such as analog balancing and reverb. You can perform DSP operations through a computer CPU or a specialized DSP chip. The difference is that the processing of a specialized
