Java and other Programming Languages

Engels (2016) has done a great comparison based on performance for Java and C++. In his study, he states “To demonstrate that, I’ve developed a set of simple benchmarks that test some of the critical aspects of the software used in a trading system implementation: network performance (Network), calculation performance (BlackScholes) and multi-threaded performance (WorkQueue)“. Following are the results (rounded to 2 decimal places) of his study:

C++ Java
Total Time (secs) USec Per Op Total Time (secs) USec Per Op
Network 3.30 6.61 3.60 7.22
BlackScholes 2.46 0.49 3.09 0.62
WorkQueue 3.05 0.61 1.19 0.24
BlackScholes Improved 0.38 0.08 0.56 0.11
BlackScholes Improved #2 0.19 0.04 0.19 0.04

Engels (2016) concludes “In summary, it is clear that the raw performance of modern Java is equal to, if not superior to C++ systems, and that the quality of the code is the most important factor in the performance of the system.”
