Free Product Sheet

How does it work?

Liberica JDK Performance Edition offers versions of JDK 8 and JDK 11 that have the core JVM and HotSpot from JDK 21 baked into the legacy JDK 8 and JDK 11 builds. Updating just one component of your stack enables you to maintain compatibility while still benefiting from the enhancements of Java 21.

This integration is not just about incorporating newer features; it's about harnessing the power of JDK 21 to optimize key performance metrics: startup time, throughput, and latency.

Whether you're working with legacy systems or constrained by specific JDK requirements, Liberica JDK Performance Edition empowers you to unlock efficiency and some features of JVM 21 without sacrificing compatibility.

Liberica JDK Performance Edition compared to a vanilla OpenJDK build

We validated the performance of Liberica JDK Performance Edition using the Spring PetClinic application and Liberica JDK 8 Standard for a comparison. The results of our studies demonstrate significant improvements:

  • 126% higher compression speed
  • 149% higher decompression speed
  • +100% higher SpecJBB Critical JOps
  • +43% higher SpecJBB MaxJOps with G1GC on small-memory configuration
  • +138% higher SpecJBB CriticalJOps by switching from jdk8 G1GC to jdk8perf ZGC on small-memory configuration
  • -99.99% BigRamTester max operation latency when switching from jdk8 G1GC to jdk8perf ZGC
  • 10% better average performance

These enhancements highlight the superior efficiency and performance of Liberica JDK Performance Edition over a standard OpenJDK build.

Compression improvement

Liberica JDK Performance Edition includes zlib-ng, a zlib data compression library for the next generation systems. It takes the performance of compression/decompression operations to a new level as compared to OpenJDK packages with a standard zlib:

  • 120% faster compression than OpenJDK 11
  • 142% faster decompression than OpenJDK 11

Zlib-ng performance measurement was done with

  • Intel(R) Xeon(R) Platinum 8259CL CPU @ 2.50GHz
  • Memory: 384GB
  • OS images: RHEL-8.2
  • Data sets: Large Calgary Corpus
