If you do stuff like that, use a profiler and identify and fix your real performance bottlenecks. As opposed to applying premature optimization blindly. Same with GC tuning. This has gotten easier over the years. But there are still lots of tradeoffs here. There are plenty of fast performing databases and other middleware written in Java. The JVM is a popular platform for that kind of thing for a good reason. Writing good software of course is a bit of a skill. Benchmarks like this are kind of pointless. Doing an expensive thing in a loop is slow. Well duh. Don't do that.
