Brief introductionMulti-mechanize is an open-source performance and load testing framework that concurrently runs multiple Python scripts to generate load on a Web site or service (a composite transaction). The test output report is saved as HTML or JMeter-compatible XML. Multi-mechanize is most commonly used for Web performance and Scalability (scalability) test

When using Python to write background tasks, it is often necessary to use the output log to record the state of the program running and to save the details of the error when an error occurs, so that you do not debug and analyze it. Python's logging module is a good helper in this case. This article introduces the performance of the log logging module in Python an

This article mainly introduces several methods for improving python performance, with code reference examples. For more information, see Some solutions for improving python performance. I. function call optimization (spatial span to avoid memory access) The core of program optimization is to minimize the Operation Sp

print a bit, the results found that the program consumes most of the time spent in the face, you can use the Time.time () method to calculate the time consumption.(7) I think the performance of several points, one is batch operation, batch submission, the second is to modify the front of a lot of parameters, the third is to reduce unnecessary operation and output of the program. Of course, and online those 1000W data a few seconds to fix the differen

The impact of Python exceptions on code running performance.Preface The exception handling capability of Python is very powerful, but poor use may also bring negative effects. I usually like to use exceptions when writing programs. Although it is better to adopt a defensive encoding method, It will be lazy to handle exceptions. Occasionally, I think about the impact of exception handling on

Before using JS to write the project, the project team used the component mode, has been feeling very good. Recently, new projects have been made with Python, and the project structure continues the component model. There has been no understanding of the performance of function calls, and today it was a whim to test and write some test codeA few classes are defined first:classA (object):defTest (self):Passc

1. The use of measuring tools, quantitative performance can improve performance, commonly used timeit and memory_profiler , in addition to, profile cProfile , hotshot etc., memory_profiler used psutil , so can not track cpython the expansion; 2. c to solve time-consuming processing, c is synonymous with efficiency, and Python is the main way to solve the problem

The content here is just a few of the things I've learned from reading Python's high-performance programming for a better understanding of the python mechanism. I am not currently engaged in computational-intensive work: artificial Intelligence, data analysis, etc. Just read the book out of curiosity. Many people think that Python cannot achieve high
