It is necessary to perform a performance test on a system that has more users than the millions portal and the Olympic booking system. Or just like the jokes that appear at the product presentation, the question that the venture capitalists ask is how many users the site can support at the same time, and the project manager says it hasn't been tested. The whole audience is in uproar ....The first step in performan

Overview
With the development of Web application technology and the rapid popularization of Web applications, the performance and service quality of web system becomes more and more important. Performance testing plays a more and more important role in the quality assurance of software. Performance test is to test the
Defined:
is to test the performance of the system by simulating various normal, peak and abnormal load conditions in a specific hardware, software, and network environment through automated test tools.Includes: execution efficiency, resource occupancy, stability, security (stress testing is a safety test), compatibility (class files can be placed on the compatibility platform, such as the program and b
System performance, for a software system, including: execution efficiency, resource occupancy, system stability, security, compatibility, reliability, scalability and so on.
A performance test is a class of tests that are implemented and executed to describe and evaluate the performance-related characteristics of a test object.

iterations), I can find that, data insertion performance may be as low as several hundred records per second during data migration. In fact, I think you can manually split the database or manually split the historical database. Do not rely on this automated sharding, because the data is placed in the correct position at the beginning, and the efficiency of the relocation is unknown. I personally think that it is more appropriate for a single MongoDB
Before you try to speed up your website in the code, determine the real cause of slow Website access. This article collects useful WEB services and tools to help you diagnose and analyze your website and give you a more comprehensive understanding of your website performance.
Website loading speed is an important factor that determines the website level and deserves special attention from webmasters. The reason is very simple. No one is willing to wai

1 Performance Test process 1.1 performance test plan stage
The main work of the test plan phase is as follows:
1. Define the test object
2. Define test objectives
3. Define the Criteria for passing the test
4. Plan the Test Progress
5. Plan testing participants (requirements, development, testing, O M and config
Performance testing includes execution efficiency, resource occupancy, system stability, security, compatibility, reliability, scalability, and so on, which is a type of test that is implemented and executed to describe and evaluate the performance-related characteristics of the test object. Performance
Performance testing often verifies that the software's capabilities are reused under normal and system conditions to meet performance metrics, or that the new version is not slower than the old version. Generally also check the system memory capacity when running the program will not be lost.Method:SEI Load Test Planning processGoal: Generate a clear, well-unders
To a certain extent, the website loading speed is the key to determining the success of the website. If you are the website owner, you must know the importance of website speed. No one is willing to wait for a long time to open a webpage. In other words, if your website is opened slowly, a large number of visitors will be lost, and the domino effect may even be adversely affected.
We recommend 12 well-selected website loading speed and performance
