. When a query is executed, SQL Server does not read more or less data than is actually required, so when executing the same query on the same dataset, the resulting logical read numbers are always the same.Why is it important to know the logical read value of SQL Server when executing queries in tuning query performance? Because this number does not change each time the same query is executed. So, when it

consumption. At the cost of a single performance loss, but because it reduces CPU consumption, for multi-threaded applications, it improves the overall average performance.(Similar scenarios in actual Java applications, where the best way to do this is to use the wait/notify mechanism instead)For other similar cycles too many times, regular, calculation and so on caused by CPU us too high condition, you ne

Label:Original: SQL Server Performance Tuning Training IntroductionHello everybody, this is the first blog post I wrote in the blogging park, and the reason I want to open this blog is a record of my interest in MS SQL Technology learning. As a computer professional graduates, their own grasp of the technology always feel very superficial, Bo and not specialized, until now I find their interests, so I foun

There are very few courses on Java performance Tuning, so a comprehensive and in-depth introduction to Java performance Tuning, North wind is exclusive, special lecturer, more than 10 years of Java development work experience, Senior software development system architect, this set of courses are years of work experienc

The JDK itself provides many convenient JVM performance tuning monitoring tools, in addition to the integrated VISUALVM and Jconsole, there are JPS, Jstack, Jmap, Jhat, Jstat and other small tools, this blog hope to play a useful, Let's start to understand the common tools for tuning JVM performance.In real-world enterprise Java development, sometimes we encounte

PrefaceThis article continues to explain how to tune the concepts that are relevant to performance optimization in the previous chapter. Code optimization is the most common of us, but there are also software architectures, JVM virtual machine tiers, databases, and operating system levels that can be tuned in various ways to improve performance. The ChaseGeneral steps for optimization:If there is a problem

In earlier articles, the detect methodology in performance tuning was mentioned, and the Detect methodology was briefly reviewed here.Discover the problem: finding problemsExplore The conditions: Reasons to exploreTrack down possible approaches: providing a possible solutionExecute the most likely approach: perform the best possible solutionCheck of Success: Confirm success (if not successful, repeat the ab

The five articles will explain the principles of Java Program Performance tuning, especially the necessary knowledge in this process and the need to determine whether your program needs tuning. It also describes the problems you may encounter during tuning. At the end of this

There are many optional tools, such as what you know, what you like, or what you want to learn. The most important thing you need to remember is to make sure that you know your benchmark data before you start the modification operation. Performance
