Abstract

Network programming is very important for next generation of distributed DAQ system. Java has powerful functionality not only in GUI but also in network programming. But, execution speed of Java program is slow on Java interpreter. For evaluating the DAQ parameters, we have investigated various benchmark programs on Java interpreter, Java Just-In-Time compiler and Java native code compiler which generates native codes, and evaluated the performance of them in comparison with that of the C native codes. We found that the performance of the Java native code compiler was nearly as good as that of the C native codes. Hence, a prototype of Java-based DAQ has been developed and evaluated. The result showed that the prototype was fast enough as first stage of the development. Our goal is to establish 3-tier (DAQ client, DAQ server and DAQ database) model for the DAQ
