performance testing using jmeter

The company recently to read and write the separation of middleware, intends to now more popular middleware for performance testing. The first Test is atlas.This test is divided into two parts, (1) The performance comparison between Atlas and direct DB, (2) The effect of event-threads parameters on the performance of A

A problem during performance testing is the time interval. Many time functions can obtain the time to obtain the time interval. I will not repeat many articles in this regard. Here I only provide some basic information to facilitate my own performance testing: (1) c language time functions clock () and clock_t: The C l

Some time ago, in Ali mother new room pressure test process used in the LR test Oracle, with the DBA (landlords) in Hangzhou netcom New computer room for 1000 users of the pressure simulation test. The entire stress test takes two days. The following are some of the experiences: 1 The stress test process found that some of the SQL scripts performed very slowly and were optimized. 2 The best concurrent testing, otherwise the service is basically no p

You can configure a two-day client, one to connect to a server on a local area network, and one to connect to the server via the Internet. Such as:The purpose of

At present, most testers like to use Loadrunner with a graphical interface as a web performance testing tool. In fact, there are many open-source performance testing tools on Linux systems that are very small and open-source products. It is a good choice for testers. In the past, we used the AB tool for some time durin

. It can automatically monitor C/C ++ programs, memory Corruption, memory leakage, pointer errors, and I/O errors are detected. By using a series of unique technologies (such as SCI technology and mutation testing), we thoroughly inspect and test our code, precisely locate the correct location of errors, and provide detailed diagnostic information. Can be used as a plug-in for Microsoft Visual C ++. 16. com

PS: Today, a colleague asked me if I have a reliable mysql stress testing tool. In fact, mysql comes with a stress testing tool called mysqlslap, which is a good simulation. The following is an example. Mysqlslap is a stress testing tool officially provided by MySQL since version 5.1.4. Simulate multiple concurrent clients to access MySQL for stress

on mobile voice services, however, the performance evaluation results of traditional MANET for VOIP services are always unsatisfactory. Here, people are very concerned about whether the wireless mesh network can meet the quality requirements of users for real-time voice services. Iometrix, a professional testing company, conducted the first performance evaluatio

Although there are not many tests that focus on performance at ordinary times, this is also insufficient. performance tests are essential for testing any software product, therefore, flexible use of some performance analysis tools is required. Recently, my colleagues recommended a
