There are fewer tutorials on iOS performance tuning, and the decision to write an iOS performance Tuning series focuses on several aspects of memory leaks, performance optimization, traffic, and power analysis.Xcode has provided a very powerful performance tuning tool, combined with several third-party tools and some techniques, to optimize performance very simply.The first writing is the simplest, analyze static analysis.When iOS developers build or

(I) three major functions ① Collect and delete index, table, and cluster statistics ② Verify the structure of tables, indexes, and clusters ③ Identification table and cluster and row migration and row Link For analyze's function of collecting and deleting statistics In Oracle, we recommend that you use the dbms_stats package instead of analyze to collect optimization information. Dbms_stats can collect information in parallel and collect global infor

First, what is Jconsole?JConsole has been introduced from Java 5. JConsole is a built-in Java Performance Analyzer that can be run from the command line or in the GUI shell. You can easily monitor Java application performance and track code in Java using JConsole (or its more advanced "close relatives" VisualVM).Second, how to start jconsole If you are starting from the command line, make the JDK on PATH and run Jconsole. If booting from the GUI shell, locate the JDK installation pa

If the work in the demand analysis stage is attributed to the preparation of the requirement specification, this simplified approach is often the culprit of the problems that may arise in the later stages of the project. We recommend that you use the following steps to form software requirements: obtain user requirements, analyze user requirements, write Requirement documents, review requirement documents, and manage requirements. Next we will discuss

How does xcode analyze and detect memory leakage (iOS) and xcodeios? Although the ARC mechanism is added to iOS 5.0 and later versions, memory leakage may still exist due to the complicated mutual reference relationship. Therefore, it is important to understand the principles. This article describes how to use Instruments to find memory leaks in the program and how to use NSZombieEnabled without ARC. This article assumes that you are familiar with the
