performance profiling tools

Monitoring indicators Metrics that typically require monitoring for performance testing include: 1. Server Linux (including CPU, Memory, Load, I/O). 2. Database: 1. Mysql 2.Oracle (Cache hit, index, single SQL performance, database [/url] threads, number of data pool connections). 3. Middleware: 1. Jboss 2. Apache (including number of threads, number of connections, log). 4. Network: throughput, throughput

This article reads the reading notes for the deep understanding of Java Virtual Machine-JVM advanced features and best practices, and it organizes the performance monitoring and Troubleshooting section of the virtual machine.About the two parts of the guide map or hope that you can personally test the experience, there are a lot of articles on the Internet, here are excerpts from several individuals think good articles for reference: Jstat/ji

Label:Performance testing of code can typically be done through static or dynamic code analysis software. During the unit testing phase, a framework such as junitperf can be used to help testers perform performance testing of the method, while the execution overhead of the code can be analyzed using DevPartner Studio during the system testing phase.DevPartner Studio, Red Gate, Jtest, Jprobe, Junitperf, and xdebug are common

Android performance optimization is a frequently encountered problem in Android development, next will be the Android performance optimization of knowledge points to do a simple comb and summary, will be from the tools and code two aspects of combing. The so-called 工欲善其事 its prerequisite, this article first look at the Android

Linux performance monitoring, testing, and optimization tools There are a lot of performance tools on the Linux platform, dazzled, long-term exploration and experience found that the best to use is those long-tested, simple gadgets. System Performance Expert Brendan D. Greg

There are a lot of performance tools on the Linux platform, a dazzling, long-term groping and experience finding the best thing to use is the proven, simple gadgets. Brendan D. Gregg, a system performance expert, updated his famous talk (Linux performance Tools) and slides o

user trace file records the statistics that are executed by a user's SQL statement. Start user tracking can be at the instance level and session level. Instance level: Sets the Sql_trace initialization parameter to TRUE and generally does not advocate tracking user actions at the instance level Session level: Executes the dbms_system.set_sql_trace_in_session function, as follows EXECUTE dbms_system.set_sql_trace_in_session (8,12,true); The Dbms_system package is created using Catproc.sql. You c

PHP ~ Compare with the performance of various acceleration tools ~. Xcache has previously introduced the principles and functions of the PHP accelerator (see the PHP-FPM server of LAMP architecture), xcache as one of the currently widely used PHP accelerators, its performance than the early Xcache introduction I have already introduced the principles and functi

limit.(iii) Accelerate the compilation of JSPThe first time you access the JSP, it will be converted into Java servlet source code, and then compiled into binary. In this process, we are able to control the compiler used. By default, Tomcat uses the same compiler that executes Javac on the command line. In fact, there are faster compilers, we can use these to improve the JSP compile speed.V. Monitoring of Tomcat servers1, Tomcat's own monitoring index ServeletStep one: Increase the user access

At present, most testers like to use Loadrunner with a graphical interface as a web performance testing tool. In fact, there are many open-source performance testing tools on Linux systems that are very small and open-source products. It is a good choice for testers. In the past, we used the AB tool for some time during web p
