The main factors affecting Java performance and tuning

Key factors that affect Java performance

1 hardware configuration, such as CPU, memory, server architecture, etc. 2) operating system 3) database system and database server 4 JVM 5 Application Server 6 The impact of network Environment 7) system architecture and code writing follow the specification for performance tuning steps, from WebLogic 1 Using tools to test your system, function, module to meet performance goal 2 Discover performance bottleneck 3 reason 4 to test your hypothesis 5) if the assumption is set up, change the implementation of this section 6) test to determine whether the change can improve performance, measure the degree of performance Improvement 7) Repeat the steps above, Until you get acceptable performance. The above description is very simple, just let us find a way to explore the problem of perseverance or means.
