I wrote up the results of trying Dave Plummer's software drag racing on
z/OS.
The focus is mainly Java vs C++ because I do SMF processing in Java, and
people like to tell me Java is too slow. Results are here:
https://www.blackhillsoftware.com/news/2021/08/10/java-vs-c-drag-racing-on-z-os/
The TLDR summary:
- Initially, the Java solution was much faster than C++
- With some work, C++ matched the speed of Java
- Rewriting the Java code to match the faster C++ code made Java slower,
to the point where the results were about what you would expect in a C++
vs Java comparison
- If you have a zIIP and your CPs are not full speed, Java might be the
fastest language on your system by a big margin.
