server performance testing tools

Mysqlslap is MySQL's own benchmark tool, the advantages: query data, simple syntax, flexible and easy to use. The tool can simulate multiple clients concurrently issuing query updates to the server. The performance test data is given and the performance comparison of various engines is provided. MSQLSLAP provides an intuitive verification basis before and after M

PS: In operation and maintenance work, stress testing is a very important work. For example, before a website online, can withstand how much traffic, in the case of large traffic performance, these data indicators will directly affect the user experience. However, in the stress test there is a common denominator, that is, the results of the stress test and the actual load results will not be identical, even

Http_load a performance measurement tool based on the Linux platform. To test the throughput and load of the Web server, test the performance of the Web page. Tools are simple, lightweight, and easy to test, but only available on Linux systems, and only Web services can be tested. The database cannot be tested. The fol

The susseed returned by its result does not mean that the request was successful, such as:Enter a non-existent website, the result is still have 479 susceed4, the actual testing process, we can only go to the log to see if the server received so many requests.

For example, CSV Data set config can form a local Reiki file into a data pool. Timers (timer)Timers are used to set the wait time between operations, and the wait time is a common means of controlling the client's QPS in performance testing. The "Think Time" type in LR. JM

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

Diagnosing database performance problems as doctors diagnose patients, it is necessary to combine their own accumulated experience and rely on scientific diagnostic reports to determine exactly where the source of the problem is. In the previous three articles we introduced many methods to optimize database performance, although it is important to master the optimization skills, but the diagnosis database
