ArticleDirectory Crystaldiskmark: Atto disk benchmark: HD tune Pro: Crystaldiskinfo: As SSD benchmark: After purchasing hard drives, SSDS, USB flash drives, storage cards, and other devices, we all want to fully understand their performance, especially the disk read/write speed. Or, after the device is installed, you also want to test whether the read/write speed of the hard disk meets the manufacturer's nominal value. In

An example code about improving php program performance and load testing. if you need it, you can see how to improve the performance of your program. calculate the execution time. the following simple method can be used to calculate the execution time of a program (subtle). The code is as follows: $ start_ti... an example code about improving php program

CPU information and performance Run the command first to obtain your CPU information. you can also view it in the probe. the probe contains more details. Cat/proc/cpuinfo The main performance parameters include: the total number of cores, and the frequency of each core. In general, the single-core high frequency is not limited, which is better than the multi-core low frequency. III. hard disk I/O

of frozen funds, should not accumulate daily.All this is enough to prove that the test is not done in the imagination, even in all aspects of the brain can be thought of, we have handled good enough, however, in the face of reality testing, the program is still so fragile, need to be carefully carved, but also needIncreased testing effort, if we think that a problem after two or three test cases, there wil

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

After the first internal beta version of the software system is released, performance testing is a common problem. We need to use different tools to complete the entire test process. Next we will introduce several commonly used tools. Jmeter The basic concepts of Java open-source tools are as follows: 1. thread group: in the test, each task must be processed by a thread. All subsequent tasks must be crea

During performance testing, we often hear the terms of concurrent users, response time, and throughput. Maybe everyone understands that there is a level and depth of understanding here. I recently read the book "detailed explanation of Software Performance and case analysis" and read his explanation. It turns out that my understanding of these terms is superficia

Recently, a lot of performance testing with Sysbench, also summed up its characteristics and usage and need to pay attention to matters. Sysbench is a multithreaded performance testing tool that can perform performance testing suc

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

What is a performance test?There are many online, to say the concept must first say classification, performance testing, stress testing, load testing, capacity testing ... In my opinion, just according to different test purposes (

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 in-depth understanding. 1. Main Features of Linux Performance Testing
