The J2EE application server provides a primary solution to develop enterprise-wide applications, which uses containers to hold application components. The container framework relieve developers' burden greatly because it encapsulates all the system level services and the developers are able to use these services directly without knowing underlying details. The processing capacity of application servers is becoming more and more important with the requirements of achieving higher performance and higher scalability. This paper uses ECperf, a performance benchmark tool for application servers, to studies the performance issues of the application server OnceAS, which is developed by the Institute of software, Chinese Academy of Sciences, and presents optimization approaches including bean instance pools and high speed naming service. These optimizations are implemented in OnceAS and proved to be effective through ECperf benchmark evaluation.
