Http://www.ibm.com/developerworks/cn/linux/l-netperf/#N1003F This article first introduces some basic concepts and methods of network performance measurement, and then discusses how to test network performance in different situations based on the use of the netperf tool. When building or managing a network system, we are more concerned about the availability of the network, that is, whether the network is connected. However, we often do n

On the Internet to see the data found that most of the use of CNT (counting instructions) to do the speed, found that the instruction count of the rate of time (or the number of acquisition times) requirements are relatively high and need to write reset signal time program, the error is relatively large, and real-time display speed effect is not good.The formula for calculating the speed of the CNT instruction: rotational speed = 60/Time point x number of countsThe reason for the error amplifica

1. First, we need to determine the basic environment of the pressure measurement, mainly server, network, disk.Server CPU frequency and cache size has a large impact on the speed of program execution, in general, the impact of IO-intensive operations cache more, CPU-intensive operation of the main frequency impact more; Server CPU cores have a large impact on multithreaded programs, and for high-level languages, due to the number of CPU cores that can

Measurement of rapid development platform, the construction of the business system, in the hands of customers to use, it is generally necessary to create customer use help documents. Because the measurement rapid development platform is an integrated platform integrating C/S,B/S, it is easy to make use of HTML documents to create business system help documents.Example:---------------------------------------

Previously, the use of swingbench for the performance stress test of Oracle RAC DB was used in the most basic and intuitive graphical mode to meet most requirements.However, in some scenarios, the graphics mode may itself consume too much resources, especially when generating a large amount of test data, it is likely due to the instability of the graphics itself caused by the death of the card or even direct exit, seriously affecting the efficiency and testing experience.In the case of silent mo

maximum iops of the disk can be calculated, that isIops = 1000 MS/(tseek + troatation ),Ignore the data transmission time. Assuming that the average physical tracing time of a disk is 3 ms, and the disk speed is, 10 K, and 15 K rpm, the theoretical maximum iops of the disk is,Iops = 1000/(3 + 60000/7200/2) = 140Iops = 1000/(3 + 60000/10000/2) = 167Iops = 1000/(3 + 60000/15000/2) = 200SSD is an electronic device that avoids the time spent on track finding and rotating traditional disks and great

Android custom control series tutorial-view measurement and LayoutAs mentioned above, when a view interface is drawn on an android screen, it must go through the following phases: measure, layout, and draw, we can see these functions in the view class, and there are several functions in it: onmeasure, onlayout, ondraw. These functions are the ones we need to pay attention to when rewriting the control, let's talk about the functions and functions of t

In a cc2640r2f project over the past few days, production tests require measurement of emission current, reception current, and sleep current. It is best to measure the current according to the method, so that the module is in a specific State (launch, receive, sleep), read the current table data, this measurement method is called solution 1.However, in actual production, we hope to control the module to di

For testing, it is very helpful to manage and improve the measurement of testing costs, results and benefits. You cannot manage what you cannot see and understand, and for understanding testing, you must collect and track test process and test validity
