About this tag
Java performance coverage on WindowsForum.com focuses on how different JDK releases compare in real-world benchmarks. A recent discussion examines Phoronix testing of JDK 8 through OpenJDK 27 on an AMD Ryzen Threadripper workstation running Fedora Workstation 44 with default settings. OpenJDK 27 led most DaCapo and Renaissance workloads, though not every test, and the results suggest modern JDKs generally run typical Java workloads faster without tuning. The same thread notes that progress from JDK 8 was uneven, with some workloads regressing across releases and a few still fastest on older runtimes, while JDK 25 is treated as the LTS target.

    Phoronix has published new benchmarks comparing Java runtime performance from JDK 8 through OpenJDK 27, which reached general availability on 15 September 2026. The tests ran on a single AMD Ryzen Threadripper 9980X workstation under Fedora Workstation 44, using default settings. OpenJDK 27 took...
