I want to perform stress tests on my website. what tools or solutions do I have? RT. I hope you can give us some comments ------ solution ------------------ the AB that comes with apache is good... ------ Solution -------------------- it is not clear in Linux that some Windows users generally use the AB solution described by Lin's sister ------------------ abhtt to perform stress tests on their websites. wh

Two confusing concepts:Load Testing: by gradually increasing the complexity of the system and testing its changes, we can see how much load the system can accept when the performance is met. Stress Testing: by gradually increasing the complexity of the system and testing its changes, it can be seen that the system is in a failed state when the performance is met, It is to find out under what conditions the system performance will become unacceptable

(If the figure is small, you can Ctrl + mouse wheel to zoom)Based on the last "Legend distributed server cluster concurrent landing on-line game test results" after the logical processing stress testing, still only configured a single gateway and a single logic service in the cluster, the results are as follows:Test Case:The first step: on-line 10,000 players, and then every 10 seconds for each player to send a logical calculation request to the gatew

Webbench is famous.website Stress testTools that can test the performance of different services on the same hardware and the health of the same service on different hardware. Webbech's standard test can show us two things about the server:corresponding requests per second and amount of data transferred per second。 Webbench not only can haveQuasiThe ability to test static pages and also to test dynamic pages (asp,php,java,cgi).And he supports static or

AB is the full name of the Apache Bench,apache with the AB command is very easy to use, you can directly in the Web server to launch test requests locally. AB for all the nature of testing is based on HTTP, so it can be said that AB for the Web server Software black box performance testing, all the data obtained and calculation results can be interpreted by HTTP; Ab.exe is an Apache-brought stress test tool that has been installed after ApacheBasic us

testing is based on HTTP, so it can be said that AB for the Web server Software black box performance testing, all the data obtained and calculation results can be explained by HTTP.Test that the machine correctly installs the AB tool, where the power Shell wants to locate the current directory to bin, enter the. \ab–v command, and if the installation is correct, print out its version information.PS d:\wamp\bin\apache\apache2.2.21\bin>. \ab-vThis is apachebench, Version 2.3 Copyright 1996 Adam

I have written a stress test before using the Web bench. http://blog.csdn.net/jacson_bai/article/details/41143713But this test, the test results are very good. The downside is that you can't make a report of an icon class! Follow it. Choose Python's plot GUI mode on the Win7 64 bit and make a test report with the diagram!Reference website: http://www.pylot.org/gettingstarted.htmlEach software is installed.

Ruby on Rails is famous for its elegant MVC Architecture, which is so attractive and beautiful, while CakePHP is one of the common frameworks in PHP development. If you don't want to be bound to the traditional PHP brick-and-mortar development, you can try to switch to the MVC Architecture, but the performance and deployment problems of Rails have been worrying. The topics of comparison between the two have different opinions on the Internet, and few have seen objective and persuasive arguments
