Performance
WebSphere Application Server provides the Performance Monitoring Infrastructure (PMI) to collect data for the application server run time and enterprise applications. Use a variety of tools to monitor and analyze the performance data. Based on the data, you can tune various parameters to improve performance. WebSphere Application Server also includes performance advisors that provide additional tips to help you optimize performance.
