Abstract	This paper studies the implementations and the performance measurements of a real-time system as CORBA application with Ada95 and Java. As an example of real-time systems, a sequence control system is considered. The first purpose of the paper is to report the implementation in Ada95-CORBA, and its performance, because there seems until now, to our knowledge, no report of the implementation using Ada95 and CORBA. The second purpose of the paper is to report the performance of the implementations in Java-CORBA compared with that in Ada95-CORBA, because Java source code is translated into Java byte code, and it is executed by interpretation, although Java execution system has generally JIT (just in time compilation) facilities or Hot Spot Technology, and from the second execution cycle it is executed in the native machine code. By the measurements, the implementation in Ada95-CORBA is stable in speed and performance, while that in Java-CORBA varies widely. Based on the investigation, Ada95-CORBA and Java-CORBA can be applied to the implementation of the distributed real-time control systems such as silo mechanisms. As an appendix, a new process composition law in CSP is proposed.
