siege load test

you are going to publish an ASP program that is expected to be used by 1000 of users. You know clearly that your program can handle at least two concurrent users, because you and your partner can click on the ASP program all day without any problems. You are wondering whether two users can accurately reflect the compression capability of your program. Of course you can use standard test methods (publish your program and expect the best results), yet

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

With the increasing of traffic and the demanding of response speed, it is very important to carry out load balancing. The company's system was initially designed to take into account the planning of load Balancing, WWW static server configured Two, because the initial project time is tight, and the traffic is not high, so at that time only used one, the other in the net, just synchronized, and to play a uti

If you have been concerned about nginx, you must know what is the use of Nginx software, if your website access is increasing, a server has no way to withstand traffic pressure, then increase the number of servers to do the load bar. Do Web site load can buy hardware equipment to achieve, such as F5, but the price of hundreds of thousands of to millions, enough expensive, this article describes the Web site

Oracle RAC Load Balancing enables client-initiated connections to be efficiently allocated to instances with smaller listener loads. There are two ways to achieve client load balancing, one is by configuring the client's load_balance, one by configuring the server-side Remote_listener parameters. Both approaches have advantages and disadvantages, and they are not mutually exclusive, so they can be combined

Page front page load performance test analysis of the feasibility scheme of each toolLevy on the various browsers and tools to do the test, the choice is the Baidu home test, because it is relatively single, no multi-layered nesting and continuous loading, minimizing other effects, the

JMeter implementing a simple Web load testBrief introductionApache JMeter is a Java -based stress testing tool developed by the Apache organization. For stress testing of software, it was originally designed for web application testing, but later extended to other test areas. It can be used to test static and dynamic resources such as static files, Java applets,

time slice interruption of the process. (In Linux 2.6, the system clock interrupts the clock frequency every 1 milliseconds, expressed in HZ macro, defined as 1000, that is, 1000 interrupts per second.) System is not the same, the kernel is not the same configuration 100, 250 have. ） The clock frequency of the kernel can be known by the following command cat/boot/config-' Uname-r ' | grep ' ^config_hz= ' config_hz=100 The total number of clock interrupts per second is = number of CPUs * Number

If you have been paying attention to nginx, you must know what the nginx software is for. If your website traffic is getting higher and higher, one server can no longer withstand traffic pressure, let's increase the number of servers for load. Website load can be achieved by buying hardware devices, such as F5, but the price ranges from hundreds of thousands to millions, which is expensive. This article int

wondering whether two users can accurately reflect the compression capability of your program. Of course you can use standard test methods (publish your program and expect the best results), yet you decide to test your program's performance in advance. That's a good sign!

To perform stress testing, the middleware uses WebLogic 816, the database version is 11.1.0.6 RAC, and the stress test tool is LoadRunner 8.0. Test the load on individual nodes of a single instance and RAC environment. A multiple pool is configured on the WebLogic, and the concurrent equilibrium is divided into two nodes by using the

ASP optimization: Load Test Your ASP programIntroducedAs we move from the traditional CS-structured application to the current popular web-space program, we find ourselves trying to keep up with growing testability requirements and performance requirements. One of the biggest challenges is how to determine how many users your program can support. How do you face this challenge? Setting clear performance goa

AB command principleApache's AB commands simulate multi-threaded concurrent requests, test server load pressures, and test the pressure of Nginx, Lighthttp, IIS and other Web servers.The AB command is very low on the computer that emits the load, does not consume a lot of CPU, and does not take up too much memory, but
