AB is an Apache self-brought stress test tool. AB is very practical, it can not only the Apache server site access stress testing, but also other types of servers to carry out stress testing. such as Nginx, Tomcat, IIS, and so on.Let's start by introducing the use of the AB command:1, AB's principle2, the installation

Using Python for site stress testing under Windows, there are two essential programs that need to be installed, one Python and the other pylot. Python is an installation software that runs a Python program, while Pylot is a Python plug-in that acts as a site stress test. This article describes how to use Python Pylot for site

Today I came to an ASP. NET stress test. The environment is as follows: Language: asp.net C # Dll size: 52kb + 260kb + 20.kb + 20kb + 48kb = 20.kb Database: Access 8 MB or so single connection to Access the database 4-5 times IIS: IIS6.0 port: 80 limit: 25% Cpu usage Application pool: Independent CPU: CM520 1.6 Ghz x 1

As a qualified website architect, need to be able to carry the pressure of the whole website is very familiar with, only in this way can make a strategist, winning thousands.In particular, before the launch of a new project, the first thing to do is to simulate the user access in a staging environment, so how much access can be sustained, and in high concurrency, the performance of Web services and server hardware?We have to collect these data indicators. In order to make a correct assessment of

Brief introductionTsung is a stress testing tool that can test servers including HTTP, WebDAV, PostgreSQL, MySQL, LDAP, and Xmpp/jabber. For HTTP testing, Tsung supportsHTTP 1.0/1.1, which contains a proxy-mode session record, supports GET, POST and PUT, and DELETE methods, supports cookies and basic WWW authentication, and also supports SSL.How the Tsung Works(1) Each virtual user of Tsung is a lightweight

First, install webbench. To test the accuracy, install webbench on another Linux server, because webbench consumes CPU and memory resources during stress testing. Otherwise, it is very likely that the server will be suspended. So I switched to the centos System for webbench testing.
