Sun SPARC Enterprise T5240 with 1.6GHz UltraSPARC T2 Plus Beats 4-Chip IBM Power 570 POWER6 System on SPECjbb2005
Significance of Results
A Sun SPARC Enterprise T5240 server equipped with two UltraSPARC T2 Plus processors at 1.6GHz delivered a result of 422782 SPECjbb2005 bops, 26424 SPECjbb2005 bops/JVM. The Sun SPARC Enterprise T5240 consumed an average of 875 Watts of power during the execution of the benchmark.-
The Sun SPARC Enterprise T5240 server running 2x 1.6 GHz UltraSPARC T2 Plus processor delivered 5% better performance than an IBM Power 570 with 4x 4.7 GHz POWER6 processors as measured by the SPECjbb2005 benchmark.
- The Sun SPARC Enterprise T5240 server equipped with two UltraSPARC T2 Plus processors at 1.6GHz demonstrated 10% better performance than the Sun SPARC Enterprise T5240 server equipped with two UltraSPARC T2 Plus processors at 1.4GHz.
- One Sun SPARC Enterprise T5240 (two 1.6GHz UltraSPARC T2 Plus chips, 2RU) has 2.3 times the power/performance than the IBM Power 570 (8RU) that used four 4.7GHz POWER6 chips.
- The Sun SPARC Enterprise T5240 used OpenSolaris 2009.06 and the Sun JDK 1.6.0_14 Performance Release to obtain this result.

Benchmark Description
SPECjbb2005 (Java Business Benchmark) measures the performance of a Java implemented application tier (server-side Java). The benchmark is based on the order processing in a wholesale supplier application. The performance of the user tier and the database tier are not measured in this test. The metrics given are number of SPECjbb2005 bops (Business Operations per Second) and SPECjbb2005 bops/JVM (bops per JVM instance).
Key Points and Best Practices
- Each JVM executed in the FX scheduling class to improve performance by reducing the frequency of context switches.
- Each JVM was bound to a separate processor containing 1 core to reduce memory access latency using the physical memory closest to the processor.
