....0.6 sec on the tested platforms. Our experience has been that this is not an impediment to real time system performance, though we avoid virtual methods where not needed. Furthermore, modern compilers implement strategies for replacing indirect virtual method calls with direct nonvirtual calls [35]. The results for the IRIX C and Microsoft VC compilers indicate well optimized virtual method calls. 7.2 The Cost of Polymorphism Polymorphism facilitates run time changes in object behavior. Real time systems often require predictable behavior of all components. Initially, the flexibility ....
