node js performance testing

. js is undoubtedly the favorite. Anyone who has ever had the simplest knowledge of node has been told that it is "non-blocking" and that it can handle I/O effectively. In a general sense, this is true. But the devil hides in the details, and when it comes to performance, the way this sorcery is implemented is crucial. In essence, the paradigm of

heap memory ZoneVar hd = new memwatch. HeapDiff ();// Your code here...Var diff = hd. end (); • There is also a function that is useful in testing and can trigger the Garbage Collector function. Okay, there are four points in total.Var stats = memwatch. gc (); Memwatch. on ('stats',...): Post-GC heap statistics Node-memwatch can produce a memory usage sample immediately after a complete garbage collection

JMeter is an Apache Jakarta project that is used for software stress testing (Load test), which allows for stress testing not only for HTTP, but also for databases (via JDBC), FTP, Web Service, Java objects, and more. Recently, it was used in our project. Our project is based on the BEA WebLogic, a Java EE project that deploys 3 Java EE applications in one domain, thus weblogic memory garbage collection dur

With the rapid development of various wireless data networks, the market has already put forward demanding requirements for various technologies. Only technologies that meet user needs can survive well. The Mobile Self-Organizing Network (MANET) originating in the military field has received crazy attention from various research organizations since the end of the last century, because it is easy to deploy, self-managed, and does not rely on infrastructure and other features to meet the needs of

Sysbench installation and performance testing Http://imysql.cn/node/312 Sysbench is a modular, cross-platform, multi-thread benchmark testing tool used to evaluate the database load of different system parameters. For details about this project, see: http://sysbench.sourceforge.net. It mainly includes the following

Alibaba technical article: Talking about Node. js and PHP process management, PHP occupies half of the server programming language, just as Wang Feng is in the music circle. As Node. js gradually stepped onto the stage of server-side programming, the debate on the advantages and disadvantages of PHP and

Guide Understanding the application's input/output (I/O) model means the difference between the planned processing load and the brutal actual usage scenario. If the application is small and does not serve a high load, it may have little impact. But as the application load goes up, using the wrong I/O model may cause you to stomp around and be scarred. As with most scenarios where multiple solutions exist, the focus is not on which approach is better, but on understanding how to wei

of Node is the construction of high-performance, highly scalable Internet applications-because it can handle massive and high-throughput concurrent connections. Its working principle is quite interesting. The traditional network service technology generates a new thread for each new connection request. This new thread will occupy the system memory and eventually occupy all available memory.

JMeter is an open source project for the Apache organization, which is a tool for functional and performance testing, with 100% in Java and the latest in 2.2.3. You can download the source code and view the related documents to http://jakarta.apache.org/jmeter/index.html. This will show you how to test your Web application using JMeter.1. jmeter function FieldJMeter can be used to test the

Original : server-side I/O performance:node vs. PHP vs. Java vs. goauthor : BRAD PEABODY The Wild goose startled the cold Absrtact: This article first briefly introduces I/O-related basic concepts, and then compares the I/O performance of node, PHP, Java, go, and gives the selection suggestions. The following is the translation. Understanding the application's input/output (I/O) model can better understand

: The user name cannot contain special characters, password must not be less than 6 characters or the correct email format and so on.Validation rules This function is to verify that the response data contains the expected information, if any, this request can pass, otherwise it will fail.My VS2010 also has several validation rules built in:For an explanation of the built-in validation rules, see here. If the built-in validation rules don't meet your needs, you can also customize your own validat

Use Javascript Generators in Node. js for details, node. jsgenerators Generators is a collaborative program (coroutine for short: coroutine) style in Javascript. It refers to the functions that can be paused and restored during execution, this function is configured with a star symbol in functi, such as function *. Some feature keywords in the function, such as y

code to be compared needs to be executed many times and usually put in a loop. Because the timer interval between Windows XP and Vista operating systems is 15 ms, this problem becomes more complex and the test is quite inaccurate, therefore, we need to ensure that the test code Runtime is longer than Ms. The following code is used for performance testing. The file is benchmark.

To bypass it, the node start module uses a connection middleware to detect whether users are from mobile devices and then sends themMobile's mobile layout (this article will introduce in detail). You can create a {viewname} _ mobile. Jade view based on a single view Convention and load it only on mobile devices. What's more powerful is, if you need to view you

JS now plays a key role in the products of many well-known companies.In this article, we will discuss not only how these benefits are achieved, but also why you use node

Website loading speed is the most important factor to determine the level of the site, worthy of special attention of stationmaster. The reason is simple, no one wants to open a Web page and so on long time, in other words, if your site is very slow to open, will churn out a large number of visitors, and even the effects of the multi-meter effect of the adverse effect. Before you dive into the code to try to improve your site's speed, determine what the real cause of the slow site access is. Thi
