Linux Performance Testing Tool Lmbench is a simple and Portable Micro-evaluation tool that complies with the ANSI/C standard for UNIX/POSIX. In general, it measures two key features: Response Time and bandwidth. Lmbench aims to give system developers an insight into the underlying costs of key operations. 1. Use and introduction of Lmbench Linux Performance

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

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

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

. 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. compuware devpartner for Visual C ++ boundscheck

Recently, sysbench has been used for many performance tests. It also summarizes its features and usage and precautions. Sysbench is a multi-thread performance testing tool that can perform performance tests such as CPU, memory, IO, and database. However, most of the time I use it to perform oltp tests on databases (MyS

The previous approach to performing performance testing in Windows was the JMeter-a complete interface test script,Before Windows performs a performance test, there are 1 performance test scripts to start with.But is this performance test script directly available on Linux?

1. Some performance indicators in the JMeter Throughput:: Throughput rate transactions per Second: Avg. Rps: Number of request per second = Total Request quantity/sec successful Hits per Seco Nd: Number of successful clicks per second Failed Hits per Second: Number of failed clicks/sec Successful Rounds: Successful request Failed Rounds: Failed request User connections: Number of user connections, that is, database connections number of deadlocks: Dat

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

MySQL performance testing is frequently used. The following describes some commonly used MySQL performance testing tools. If you are interested in this, take a look. Three MySQL performance testing tools: The MySQL Benchmark Suit
