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

The scope discussed in this paper does not include geometry reconstruction, texture reconstruction, but only three-dimensional measurement algorithm based on the existing three-dimensional triangular mesh model (the human triangular grid). In fact, the circumference measurement is a three-dimensional model with a specific plane intersection, and the intersection further analysis of the intersection of the s

Design of dynamic dip measurement system in rotating state [Date:] Source: China Power Grid Author: Wang Chao, Gao Guowei, Pan Xue, Zhang Jun, Zhao Yu [Font:Large Medium Small] 　 0 The dip measuring module based on MEMS accelerometer has the advantages of small size, light weight, low cost, impact resistance, and high reliability. There is a large error in Inclination Measurement with

This article is from the Android Elite biography (Xu Yisheng)I wrote here, I think Xu Yisheng is really good, but also added some of their own understanding, to facilitate their own foundation to improve.If you want to draw a view, you need to take a measurement first, that is, you need to know its size and location. So we can slide it out of the screen. This process is done in the Onmeasure () method.I. Measureme
