IO Chunk Size (IOPS, 8.6 ms)135 = didn't respond ...88.6 ms24.6 ms14.6 msAs can be seen from the above data, as the system actual IOPS closer to the theoretical maximum, the response time of IO will be non-linear growth, the closer to the maximum value, the response time becomes larger, and will exceed the expectations of a lot more. Generally in the actual application there is a 70% guideline value, that is, in the IO read-write queue, when the queue size is smaller than the maximum iops of 70

Software version NX 4.0 Phenomenon: One day suddenly found that the measurement of the length of the object information, the actual pop-up information about the reality of the information message window did not pop up, thought that moved what set up, busy for a while no movement, see online also said to re-install software even system .... Fortunately found a post, said dual-monitor reality may affect this window, I carefully observe another monito

Maximum number of connections supported by Mysql serverThe performance of the host directly affects the maximum number of concurrent connections supported by the MySQL server side, such as insufficient memory to cause connection creation to fail./etc/my.conf configures the maximum number of connections that MySQL server can receive, and the performance of the host directly determines the maximum number of connections that can be created.Use the Mysqlslap tool to measure the maximum number of con

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

Similarity measurement in machine learningWhen classifying, it is often necessary to estimate the similarity metric between different samples (similarity measurement), which is usually done by calculating the "distance" (Distance) between samples. The method used to calculate the distance is very fastidious, even related to the correct classification.The purpose of this paper is to make a summary of common

Recently the company wanted to do a PM2.5 testing equipment, probably studied the PM2.5 related knowledge, as well as sharp dn7c3a006 sensor applications.The following is a brief introduction to it.1, its own dust-free voltage (nodust_v), the nominal temperature (base_temp), the two values are scanned by a QR code, such as the scan we purchased to obtain the "149190104F 1.31 * * * * 25.8", can be obtained nodust_v = 1310mv, Base_temp = 25.8 ℃ (but these two values only serve a certain reference,

First, IntroductionThe Android system must measure the view before drawing the view, which tells the system how much view to draw. This process is performed in the Onmeasure () method. The Android system provides the Measurespec class by helping us measure the view.The measurement mode can be divided into three types: Exactly: that is the exact value mode, the system uses the exactly mode by default. At_most: The maximum mode, when the co

say something in front.when one of our view interface is drawn on the Android screen, we actually have to go through these steps measure, layout, draw, we can see these functions in the view class, then there are several functions are onmeasure, OnLayout and OnDraw are some of the functions we need to be aware of when we rewrite our controls, so let's talk about the functions and roles of these functions. onmeasurejust as the name of this function is the mea
