But as long as it is a multi-server cluster, we can calculate the load capacity of multiple machine clusters through the test results of 1 machines, with the additional consideration of load balancing and routing pressure, such as bandwidth, speed, latency, etc. But if all the changes in 1 machines, then we can only do some of the indicators on the calculation, can be easi

."Intermediate response time" is the median response time for a period of time, 50% response time, and half of the server response time is below that value and the other half is above that value."90% response Time" 90% of transaction response time is smaller than this value over time. Response to the overall response speed, and the 10% timeout rate above that value. is one of the important indicators used to assess system capacity.Minimum response time for the Min. reflects the fastest processin

good, people are also temporary formation. But the latter team was successful and the previous team failed. The author has a few gains1 successful team complex tasks are concentrated in a small number of hands. Other programmers take on a lot of work, but not hard. The team that failed is almost everyone's workload is similar, the average complexity is high.2 successful teams each work in multiple areas. Failed teams each work in a very small area3 Successful team of people innovation, also ini

Send monitoring metrics to the internal mailbox in LinuxDatabase health monitoring is a very important task. An important indicator/KPI monitoring result has a dedicated collection, monitoring, and alarm system for relevant tasks.Some indicators that are not very important or are still in the design and debugging phase, I just want to send them to my own mailbox. This article describes the process of configuring mail to send monitoring data on the ser

In addition, many features of Android are more power consumption (such as screen, Gps,sensor sensor, wake-up mechanism, CPU, network, et

) Jaccard distanceThe concept opposite to the Jaccard similarity coefficient is the jaccard distance (jaccard distance). Jaccard distances can be expressed in the following formula:The Jaccard distance is used to measure the sensitivity of two sets by the proportion of the elements in each of the two sets.(3) Application of Jaccard similarity coefficient and Jaccard distanceThe Jaccard similarity coefficient can be used to measure the similarity of samples.Sample A and sample B are two n-dimensi

. The memory resources of the mobile device are very limited, and the private memory allocated for each app process is limited. On the one hand, we should reasonably apply for memory use, so as not to cause frequent GC (garbage collection mechanism) impact performance and large object application memory overflow; On the other hand, we need to release memory in time to avoid a memory leak.ElectricityMobile devices have very limited battery power relative to the PC, which is especially important t

Content is the most valuable part of a website. The only purpose of a user's access to your website is to obtain valuable content, rich content, and accurate content, the constantly updated content is three elements of a successful website. Of the 101 metrics of the perfect website, 23 are about content. We put the content first. In fact, you should focus 80% on the content, the 23 content indicators are: Rich Content It is hard to imagine the disapp

In the analysis of the site should be integrated use, in order to make the correct suggestions for improvement measures. For example, if a product is not focused, but the conversion rate is high, we should analyze how, and another product is very high, but the conversion rate is very low, we should analyze how

tcpdump to grab the packet, when the problem is reproduced (such as the log display or a state appears), you can end the capture, and the tcpdump itself with-c/-w parameters, you can limit the size of the crawl packet storage file, When this limit is reached, the saved packet data is automatically rotate, so the total number of packets is still controllable. After that the packet took off the line, with Wireshark want to see how to see, not happy! Tcpdump Although there is no GUI interface, but

higher the speedup, the more obvious the optimization effect. The Amdahl law gives the relationship between speedup and system parallelism and number of processors. Assuming that the speedup ratio is speedup, the program that must be serialized within the system is the F,CPU processor number n, which is:speedup≤1/(f+ (1-f)/n) Example: under a dual-core processor, a program execution step consists of 5 steps, of which 3 steps must be serial, so its serialization weight is f=3/5=0.6,n=2. Accordin

, the Markov distance between two points is independent of the unit of measurement of the original data, and the Markov distance between the normalized data and the central data (that is, the difference between the original data and the mean) is the same as that between two points. The Markov distance can also exclude the interference of correlations between variables. Cons: Its disadvantage is that it exaggerates the effects of small variables that change.Reference:Http://www.cnblogs.com/daniel
