In the existing design of web server architecture, data encryption technique is used to keep the reliability, stability, and safety of web service. But the use of data encryption technique wastes the work of cpu while decreasing throughput of web server and increasing average response time so that it shows negative effect on the capacity of web application server. Also, the latest web applications require security and safety for the safe internet communication. Therefore, this paper suggests the improved web server which uses thread pool and Non-blocking I/O adding new web service modules to the existing web server for the safe web service, provides reliability and safety to show the safe web service capacity. And we compare and evaluate the safety and capacity through experiment on the existing traditional Tomcat based web server and the proposed system to evaluate the safety and capacity of the proposed web server system.

Recently, the mobile Internet is rapidly changing environment in a user's web server performance requires frequent connection is difficult because the proper response is needed to improve the performance of web services engine. Therefore, the goal of this paper is to improve the performance of web services for the installation of additional access to users regardless of tomcat servlet container and process the request and to shorten processing time of SOAP (Simple Object Access Protocol) message of the server structure to of for web mobile services. The web-sever structure is consists of user demand receiver, web document processor, SOAP protocol processor, NBTM(Non-Blocking and Thread Manager) manager, session manager. The system fully supports a standard web-service protocol, reduces the message processing time and communication overhead of mobile web-service system in Web 2.0 and overhead of server, and confirms the improvement of capability by comparing and evaluating Web 2.0 standard mobile web-service system through delaying achievement evaluation by the experiment of realization in Web 2.0 environment.
