Tune performance
You can adjust various settings to improve the performance of your application server and applications. WebSphere Application Server also provides performance advisors to help you optimize performance. These performance advisors use the PMI data to suggest configuration changes based on which settings might need to be adjusted for your environment. For more information about PMI data, see Performance Monitoring Infrastructure (PMI). For information about the performance advisors, see these topics:
Use the Performance Advisor in Tivoli Performance Viewer
The Performance Advisor in Tivoli Performance Viewer provides information to help you optimize performance. This topic describes how to configure and use the Performance Advisor.Use the Runtime Performance Advisor
The Runtime Performance Advisor provides information to help you optimize performance. This topic describes how to configure and use the Runtime Performance Advisor.These topics provide information about tuning parameters that you can adjust to optimize performance:

This topic provides detailed information about parameters that can affect performance and how to change them.Application assembly performance checklist
This topic describes settings that you can configure during application assembly to optimize application performance.Java memory tuning tips
This topic provides information to help you optimize Java virtual machine performance.Queuing network
This topic describes how to tune the components of the queueing network to optimize performance.Troubleshoot performance
This topic describes some common performance problems and the actions that you can take to correct the problems.These topics provide performance tuning information for specific components of WebSphere Application Server:
- Object Request Broker tuning guidelines This topic provides information about improving the performance of the ORB service.
- Set custom properties for an HTTP transport Set custom properties to improve the performance of HTTP transports.
- Pre-touch tool for compiling and loading JSP files The pre-touch tool can improve application server startup time.
- Dynamic cache service The dynamic cache service stores some information, such as servlet output, to reduce request processing time.
- Access intent policies An access intent policy is a set of properties that governs data access for enterprise bean persistence.
- Tune session management You can specify session management settings such as which data is written to the database and how often data is written to the database.
- Connection pooling Connection pooling maintains a pool of network connections for your application server. As a result, the application server does not need to continually create new connections.
- Tune your security configuration If you enable security, performance is adversely affected. This topic provides tips to help you reduce the negative impact that security can have on performance.
