  HIJING++ (Heavy Ion Jet INteraction Generator) is the successor of the widely
used original HIJING, developed almost three decades ago. While the old
versions (1.x and 2.x) were written in FORTRAN, HIJING++ was completely
rewritten in C++. During the development we keep in mind the requirements of
the high-energy heavy-ion community: the new Monte Carlo software have a well
designed modular framework, therefore any future modifications are much easier
to implement. It contains all the physical models that were also present in
it's predecessor, but utilizing modern C++ features it also includes native
thread based parallelism, an easy-to-use analysis interface and a modular
plugin system, which makes room for possible future improvements. In this paper
we summarize the results of our performance tests measured on 2 widely used
architectures.
