Performance Evaluation of HLA RTI Implementations

The High Level Architecture is an IEEE standard that enables distributed simulation. There are several implementations of the standard, which are providing i.a. the Run-Time Infrastructure component. This paper compares the four most known RTI Implementations, namely MAK RTI, Pitch pRTI, Portico, and CERTI, with a focus on performance evaluation. In general, Pitch pRTI was the fastest implementation for most of our experiments. CERTI performed best for big payload sizes and Portico showed an interesting oscillation pattern.
