![]() You'll benefit from a JDBC-only application if you need extreme throughput on those insertions. But how does the INSERT come to be, realistically? Is the application inserting into a single table or maybe 2 in total? Sure. Of course it is simpler and faster to run a trivial INSERT with JDBC directly, instead of adding any additional layer on top of it. This doesn't mean the comparisons are meaningful. Sure, it's not a microbenchmark, but at least, JMH correctly warms up all candidates, and then runs all the tests many many times, to be able to calculate min/max/mean execution times or throughputs, as well as standard deviations and error margins, so you can at least measure correctly. They didn't do this right, but published the results nonetheless. Did they run a single execution, rather than warming up the JVM, Hibernate, JDBC, etc.Did they compare stuff with System.currentTimeMillis() again, instead of System.nanoTime()?.They published the first very sloppy result! They didn't even bother to fix the division by zero with something more meaningful. Objects: 16 - Hibernate: 10ms / Direct JDBC: 0ms = Ratio: Infinity In all these years, I've hardly seen any benchmark performed by someone who really knew all the compared APIs and tools to an extent where they could tune each usage in a fair and truly comparable way.
