19 Jan 2016 Migration Guide from Oracle JRockit JVM to HotSpot JVM [49283]
Java, January 19th, 2016

During the 2010 JavaOne conference Oracle announced that it would merge the Oracle JRockit JVM and HotSpot JVM by incorporating the features that were only available in JRockit into HotSpot.

With JDK 7 Oracle started delivering on that vision. It completed the work with JDK 8. Customers using the Oracle JRockit JVM, in the meantime, have been receiving periodic security updates and bug fixes. CPU releases and bug fixes for Java SE 6 JRockit (R28 only) will continue to be provided until the end of JRockit for Java SE 6's extended support phase, currently scheduled for December 2018.

07 Oct 2013 Sun Server X4-2 Performance Running SPECjbb2013 MultiJVM Benchmark [33200]
Using Oracle Solaris and Oracle JDK

Oracle's Sun Server X4-2 system, using Oracle Solaris and Oracle JDK, produced a SPECjbb2013 benchmark (MultiJVM metric) result. This benchmark was designed by the industry to showcase Java server performance.

  • The Sun Server X4-2 system is 24% faster than the fastest published Intel Xeon E5-2600 (Sandy Bridge) based two socket system's (Dell PowerEdge R720's) SPECjbb2013-MultiJVM max-jOPS.

  • The Sun Server X4-2 is 22% faster than the fastest published Intel Xeon E5-2600 (Sandy Bridge) based two socket system's (Dell PowerEdge R720's) SPECjbb2013-MultiJVM critical-jOPS.

  • The Sun Server X4-2 runs SPECjbb2013 (MultiJVM metric) at 70% of the published T5-2 SPECjbb2013-MultiJVM max-jOPS.

  • The Sun Server X4-2 runs SPECjbb2013 (MultiJVM metric) at 88% of the published T5-2 SPECjbb2013-MultiJVM critical-jOPS.

  • The combination of Oracle Solaris 11.1 and Oracle JDK 7 update 40 delivered a result of 52,664 SPECjbb2013-MultiJVM max-jOPS and 20,553 SPECjbb2013-MultiJVM critical-jOPS on the SPECjbb2013 benchmark.

23 Sep 2013 SPARC T5-2 Delivers Best 2-Chip MultiJVM SPECjbb2013 Result [32992]
Benchmark designed to show modern Java server performance

SPECjbb2013 is a new benchmark designed to show modern Java server performance. Oracle's SPARC T5-2 set a world record as the fastest two-chip system beating just introduced two-chip x86-based servers. Oracle, using Oracle Solaris and Oracle JDK, delivered this two-chip world record result on the MultiJVM SPECjbb2013 metric. SPECjbb2013 is the replacement for SPECjbb2005 (SPECjbb2005 will soon be retired by SPEC).
