web application performance testing using jmeter

1. AB Introduction AB full name Apache Bench, is an Apache with a small tool, it can simultaneously simulate multiple concurrent requests, testing the maximum load pressure of Web servers such as Apache. Through a simple example, this paper introduces the performance test of Web pages

: 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

PS: Stress testing is an important task in operation and maintenance. For example, before a Web site online, can withstand the number of visits, in the case of large traffic performance, these data indicators will directly affect the user experience. However, there is a common in stress testing, that is, the results of

PS: Site Performance Stress testing is an essential part of the performance tuning process. It is only when the server is under high pressure that it can truly reflect the problems exposed by the various settings. Apache has a self-contained program called AB that can be used for Web site stress

start a request to the client to receive the last byte. The unit of the request response time process is typically "seconds" or "milliseconds".Transaction response TimeA transaction may consist of a series of requests, and the response time of a transaction is primarily for the user, and is a macro concept that is presented to the user in order to explain the business response time. For example, the response time for a cross-line withdrawal transaction is made up of a series of requests.Through

1,swingben Introduction The current open source Oracle Stress testing Tools on the Web are mainly ORABM and swingbench, and because ORABM does not support Oracle 11g versions, the test uses Swingben for stress testing. In addition, Swingbench can also test the RAC. Swingbench is an Oracle stress testing tool developed

PV per day)Peak QPS and machine calculation formulasPrinciple: 80% of visits per day are concentrated in 20% of the time, 20% times called peak timeFormula: (Total PV number * 80%)/(number of seconds per day * 20%) = Peak Time requests per second (QPS)Machine: Peak time per second QPS/single machine for QPS = Required machineQ: How much QPS does this machine need per day for 300w PV on a single machine?Answer: (3000000 * 0.8)/(86400 * 0.2) = 139 (QPS)Q: If the QPS for a machine is 58, how many

WEB performance testing tools are mainly divided into three types: one is to test the page resource loading speed; the other is to test the page rendering speed and JS operation speed after the page is loaded; one is to evaluate and analyze the page in general. ~~~ If anyone has better tools, share them with us.1.
