Sun SPARC Enterprise T5240 World Record SPECjbb2005 multi-JVM 2-chip performance

Wednesday Apr 09, 2008

The Sun SPARC Enterprise T5240 with two 1.4 GHz UltraSPARC T2 Plus processors obtained the best multi-JVM 2-chip results on the SPECjbb2005 server-side Java benchmark.

A Sun SPARC Enterprise T5240 server equipped with two UltraSPARC T2 Plus processors at 1.4GHz, delivered a World Record 2-chip result of 373,405 SPECjbb2005 bops, 23338 SPECjbb2005 bops/JVM. The Sun SPARC Enterprise T5240 consumed an average of 770 Watts of power to obtain this result.

One Sun SPARC Enterprise T5240 server (two 1.4 GHz UltraSPARC T2 Plus chips) demonstrated 11% better performance over the IBM p550 result of 333,779 SPECjbb2005 bops, 83445 SPECjbb2005 bops/JVM which uses four 4.2GHz POWER6 chips. The Sun T5240 server has 3.25X better SWaP and 50% better power-performance than the IBM p550.

One Sun SPARC Enterprise T5240 server (two 1.4 GHz UltraSPARC T2 Plus chips) demonstrated 23% better performance over the Dell 2950 result of 303,130 SPECjbb2005 bops, 75783 SPECjbb2005 bops/JVM which uses two 3.1GHz Intel Xeon X5460 chips. The Sun T5240 server has similar power-performance compared to the Dell 2950.

One Sun SPARC Enterprise T5240 server (two 1.4 GHz UltraSPARC T2 Plus chips) demonstrated 2.4X better performance over the HP rx6600 result of 158,174 SPECjbb2005 bops, 39544 SPECjbb2005 bops/JVM which uses four 1.6 GHz Intel Itanium 2 chips. The Sun T5240 server has 12.5X better SWaP and 3.5X power-performance than the HP rx6600.

One Sun SPARC Enterprise T5240 server (two 1.4 GHz UltraSPARC T2 Plus chips) demonstrated 4.6X better performance over the HP rx2660 result of 80,884 SPECjbb2005 bops, 80884 SPECjbb2005 bops/JVM which uses two 1.6GHz Intel Itanium 2 chips. The Sun T5240 server has 3.4X better SWaP and 3.5X power-performance than the HP rx2660.

One Sun SPARC Enterprise T5240 server (two 1.4 GHz UltraSPARC T2 Plus chips) demonstrated 2.1X better performance over the IBM p570 result of 175,474 SPECjbb2005 bops, 87737 SPECjbb2005 bops/JVM which uses two 4.7GHz POWER6 chips. The T5240 server has 5.7X better SWaP and 3X power-performance than the IBM p570.

One Sun SPARC Enterprise T5240 server (two 1.4 GHz UltraSPARC T2 Plus chips) demonstrated 65% better performance over the IBM p560Q result of 226,291 SPECjbb2005 bops, 28286 SPECjbb2005 bops/JVM which uses eight 1.5GHz POWER5+ chips. The T5240 server has 17.2X better SWaP and 4.5X power-performance than the IBM p560Q.

The SWaP metric is a measure of server efficiency ratio that includes system performance, power and space consumption on a specific benchmark. (SWaP = Perf /[ Space (RU) x Watts ] )

Power-performance is computed as watt/performance. Since power-performance is related to price/performance they are both calculated with performance in the denominator.

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).
