Java Screams on Sun UltraSPARC T2


The UltraSPARC T2 has arrived and the Sun HotSpot JVM is ready.  We've spent the last several months optimizing Sun's JVM for US-T2 and the day has finally come to share what we've been working on.

Two new SPECjbb2005 world records! 
  • Sun SPARC Enterprise T5120 and T5220 servers delivered a World Record SPECjbb2005 Single Socket result of 192,055 SPECjbb2005 bops, 24,007 bops/JVM.
    • 9% faster than IBM p570 with 2 x 4.7Ghz Power 6 Processors!
    • 4X less space, 2X less power!
  • Sun SPARC Enterprise T5120 and T5220 servers delivered a World Record Single JVM result for all systems with 8-cores or less.
    • Beats all single JVM results from Dell and HP!
Record Breaking Perfomance

The Sun SPARC Enterprise T5120 and  Sun SPARC Enterprise T5220 servers equipped with a single UltraSPARC T2 processor at 1.4GHz, delivered a World Record single-chip result of 192,055 SPECjbb2005 bops, 24,007 SPECjbb2005 bops/JVM.  An average of 464 Watts of power was used to obtain this result.  This result beats the previous SPECjbb2005 single-chip world record  by 71%.






Record Breaking Scalability

The Sun SPARC Enterprise T5120 and Sun SPARC Enterprise T5220 servers delivered a World Record  single-chip, single-JVM result of 170,153 SPECjbb2005 bops, 170,153 SPECjbb2005 bops/JVM.    This result beats all single-JVM SPECjbb2005 results from Dell and HP, and all 8-core or less single-JVM results from IBM.  To top it off, the  64-bit single-JVM SPECjbb2005 result is within 13% of the performance of the 32-bit multi-JVM result of 192,055 SPECjbb2005 bops, 24,007 SPECjbb2005 bops/JVM, highlighting the flexibility of the Ultra SPARC T2 and Sun HotSpot JVM technology.





Reliable Performance: Sun's HotSpot JVM


Rock solid reliable performance is at the heart of HotSpot JVM development at Sun.  Our dedicated effort has allowed us to deliver performance optimizations into JDK 6 update releases in a highly reliable fashion, with our first ever JDK 6 performance release coming your way in December 2007.   Stay tuned for more information on the performance release and all of the cool optimizations we're working on for all of our supported platforms.

I wasn't aware the any IBM POWER6 benchmarks had been published, are you sure the p570 isn't a POWER5 machine? It's not completely done yet, is it?

Impressive none the less. Great work Sun.

The IBM p570 result is indeed a 2 x 4.7Ghz (4-core, 8-thread) Power 6. Here's the result:

Thanks for your interest!

"JDK 6 performance release" - this sounds interesting - is this just java kernel ?
