What is the concept and basic purpose of Performance Testing? I think everyone knows it clearly and I will not elaborate on it. In short, performance testing is only a method in the testing process, it helps us to run our functions better. If function testing is available, easy to use, satisfying requirements, and intended for use, performance testing is nothing

Raid 10 Vs. RAID 5 performance provides a Performance Data graph that uses sqlio. EXE to generate 8 KB random reads and writes, with a performance gap nearly doubled. Disk access time = disk seek time + latency Latency = 1 minute/RPM/2 The main factor determining iops is the array'sAlgorithm, Cache hit rate, and number of disks. The array algorithms vary

"Editor 's note" Previously, read a lot about PHP performance analysis of the article, but it is written in a single rule, and the rules are not context, there is no clear experiment to reflect the advantages of these rules, while the discussion also focuses on some grammatical points. This article changes the PHP performance analysis angle, and through the example to analyze the PHP

I used to pursue new things, and found the foundation is the most important, this year's main goal is to master SQL query and SQL performance optimization.This series of "T-SQL Fundamentals" is primarily a summary of the T-SQL Foundation."T-SQL Basics" 01.

Original address: http://maoyidao.iteye.com/blog/1663193A service that is deployed on only 4 servers, writes more than 1 million rows of data to database per second, producing more than 1G of data per minute. The CPU on each server (8 cores 12G) consumes less than 100%,load 5. How is this done? Here is a description of the architecture, the core of which is an efficient buffer design, and our requirements for it are:1, the buffer should be as simple as possible2, try to avoid producer thread and

parameter that directly measures system performance.. 4.Concurrent users Concurrency is generally divided2. One is strict concurrency, that is, all users perform the same thing or operation at the same time. This operation generally refers to the same type of business. For example, in the Credit Card Approval business, a certain number of support personnel submit completed approval services at the same time. There is also a special case that all

As we all know, Mysql paging requires the use of Limit for paging. When the data size is small, the Limit performance can be imagined. For example: {code...} the preceding SQL statement has no performance problems. However, if the offset is too low, a performance bottleneck may occur. For example, {code... as we all know, Mysql uses Limit for paging. When the dat

Performance of network protocolsNow it's our turn to actually control things.The performance of network processing is not proportional to the addition of delay time.This is because the intrinsic operation of most network protocols is bidirectional information exchange.The remainder of this chapter focuses on understanding why these exchanges of information are generated and how to reduce or even eliminate t
