PHP uses ab in Apache to test the stress performance of the website_PHP tutorial
Open the installation path of the Apache server (I use WampServer). There is an executable program ab.exe in the bin directory, which is the stress testing tool to be introduced.
In the command line of Windows system, enter the directory where the ab.exe program is located and execute the ab.exe program. Note that double-clicking directly will not work correctly. 喎?http://www.Bkjia.com/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+ICAgICAgICBkOii72LO1L734yOtExcwpPGJyPgo8L3A+CjxwPiA8aW1nIHNyYz0="http://www.2cto.com/uploadfile/Collfiles/20140614/20140614091704240.jpg" alt="">
cd wampbinapacheApache2.4.4bin (Enter/enter the bin directory)
ab(Enter/)
If you see the following help information, it means ab has been successfully started
Start ab stress test
Ab -n 5000 -c 200 http://localhost/test.php
The above example indicates that the script http://localhost/test.php has been accessed 5,000 times in total, with 200 concurrency (simulating simultaneous access by 200 users).
Introduction to commonly used ab parameters:
-n: The total number of request executions, the default is 1;
-c: Number of concurrencies, the default is 1;
-t: The total time of the test, in seconds, the default is 50000s
-p: Data file during POST
-w: Output the results in HTML table format

Windows 10 vs. Windows 11 performance comparison: Which one is better? With the continuous development and advancement of technology, operating systems are constantly updated and upgraded. As one of the world's largest operating system developers, Microsoft's Windows series of operating systems have always attracted much attention from users. In 2021, Microsoft released the Windows 11 operating system, which triggered widespread discussion and attention. So, what is the difference in performance between Windows 10 and Windows 11? Which

The Windows operating system has always been one of the most widely used operating systems on personal computers, and Windows 10 has long been Microsoft's flagship operating system until recently when Microsoft launched the new Windows 11 system. With the launch of Windows 11 system, people have become interested in the performance differences between Windows 10 and Windows 11 systems. Which one is better between the two? First, let’s take a look at W

In the era of mobile Internet, smartphones have become an indispensable part of people's daily lives. The performance of smartphones often directly determines the quality of user experience. As the "brain" of a smartphone, the performance of the processor is particularly important. In the market, the Qualcomm Snapdragon series has always been a representative of strong performance, stability and reliability, and recently Huawei has also launched its own Kirin 8000 processor, which is said to have excellent performance. For ordinary users, how to choose a mobile phone with strong performance has become a key issue. Today we will

PHP and Go are two commonly used programming languages, and they have different characteristics and advantages. Among them, performance difference is an issue that everyone is generally concerned about. This article will compare PHP and Go languages from a performance perspective, and demonstrate their performance differences through specific code examples. First, let us briefly introduce the basic features of PHP and Go language. PHP is a scripting language originally designed for web development. It is easy to learn and use and is widely used in the field of web development. The Go language is a compiled language developed by Google.

Ollama is a super practical tool that allows you to easily run open source models such as Llama2, Mistral, and Gemma locally. In this article, I will introduce how to use Ollama to vectorize text. If you have not installed Ollama locally, you can read this article. In this article we will use the nomic-embed-text[2] model. It is a text encoder that outperforms OpenAI text-embedding-ada-002 and text-embedding-3-small on short context and long context tasks. Start the nomic-embed-text service when you have successfully installed o

Performance comparison of different Java frameworks: REST API request processing: Vert.x is the best, with a request rate of 2 times SpringBoot and 3 times Dropwizard. Database query: SpringBoot's HibernateORM is better than Vert.x and Dropwizard's ORM. Caching operations: Vert.x's Hazelcast client is superior to SpringBoot and Dropwizard's caching mechanisms. Suitable framework: Choose according to application requirements. Vert.x is suitable for high-performance web services, SpringBoot is suitable for data-intensive applications, and Dropwizard is suitable for microservice architecture.

The performance comparison of PHP array key value flipping methods shows that the array_flip() function performs better than the for loop in large arrays (more than 1 million elements) and takes less time. The for loop method of manually flipping key values takes a relatively long time.

Effective techniques for optimizing C++ multi-threaded performance include limiting the number of threads to avoid resource contention. Use lightweight mutex locks to reduce contention. Optimize the scope of the lock and minimize the waiting time. Use lock-free data structures to improve concurrency. Avoid busy waiting and notify threads of resource availability through events.
