Two new techniques for improving performance of reified generics without specializing types are presented. With these techniques, the cost of method dispatch is reduced by 95% from the regular self dispatching based implementation, and the cost of returning primitive value is reduced by 15% from the regular boxing based implementation. These techniques are useful to implement reified generics in Java and other JVM languages.

“…This design point has a number of consequences for the language implementations and their performance model. Much of the details are implementation-specific so we defer them to Section 6 and to the paper by Takeuchi et al [9]. However, one highlevel consequence of this design is generally true: to implement the desired semantics the language implementation's runtime type infrastructure must be able to distinguish between different instantiations of a generic class (since instantiations on different struct types will have different memory layouts).…”

To reliably write high performance code in any programming language, an application programmer must have some understanding of the performance characteristics of the language's core constructs. We call this understanding a performance model for the language. Some aspects of a performance model are fundamental to the programming language and are expected to be true for any plausible implementation of the language. Other aspects are less fundamental and merely represent design choices made in a particular version of the language's implementation.In this paper we present a basic performance model for the X10 programming language. We first describe some performance characteristics that we believe will be generally true of any implementation of the X10 2.2 language specification. We then discuss selected aspects of our implementations of X10 2.2 that have significant implications for the performance model.
