Performance Optimization Research Based On Engineering Information Manage System

Engineering information manage system is the all and the one combined with network technology and engineering manage , it takes network as platform , take engineering manage as subject, whose job effect and the systematic actual function are bound together in the process of realization , how to connect many nodes being in different region and dissimilar network and diversity environment to share and integrate the engineering data,how to insure the high-effect system operation state,and rapidly respond in real time ,and provide the customer for fluent high experiences. That is the target to process performance optimization research on engineering information manage system.First,introduce the engineering information manage system used in The China Railway Engineering Group Co.Ltd (CREC) and subsidiary engineering bureau which the author participate in designing and programing, expatiate the importance in engineering manage,List out the cause relating to many-sided performance problem such as long-range transmission , resource assignment , system respond, and analysing the causation which various problem coming into being.Furthermore,Ajax and data compression and related technologies are researched in depth,from the angle of actual application,recommend many key problem such as how to solve delaying in responding between clent and server by using Ajax technology,how to fall off transports load and lifting transfers efficiency by using data compress technology,how to design code to assign system resource rationally by union the .Net memory reclaims echanism,how to save system spending in responding by using cache output to client.Generalize a scheme using in performance optimization, to achieve ultimate purpose that improve the handling capacity and running load of system.Finally, the feasibility of optimization scheme is certified in practice.
