The blog on BestPerf entitled "Sun SPARC Enterprise T5240 with 1.6GHz UltraSPARC T2 Plus Beats 4-Chip IBM Power 570 POWER6 System on SPECjbb2005" by Kevin Kelly reports the results of this benchmarking exercise as 422782 SPECjbb2005 bops, 26424 SPECjbb2005 bops/JVM for the Sun SPARC Enterprise T5240, which is 5% better performance than an IBM Power 570 with 4x 4.7 GHz POWER6 processors as measured by the SPECjbb2005 benchmark. In the course of setting this mark, the T5240 consumed an average of 875 watts.

A further benchmark that Kelly reports is that 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.

Kelly adds as well that 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.

Further useful information in the evaluation of this benchmark is that the Sun SPARC Enterprise T5240 used OpenSolaris 2009.06 and the Sun JDK 1.6.0_14 Performance Release to obtain this result.

Performance Landscape

The bops mark set by the IBM Power 570 with four chips, eight cores and 15 threads at 4.7 GHz was 40923 and bops/JVM was 100731, as opposed to 26424 set by the T5240.

The bops for the Sun SPARC Enterprise T5240 running at 1.4 GHz was 384935 and the bops/JVM 24058. The 1.4 GHz T5240 hardware configuration included 64 GB.

One final note that Kelly includes is that each JVM executed in the FX scheduling class to improve performance by reducing the frequency of context switches, and each JVM was bound to a separate processor containing 1 core to reduce memory access latency using the physical memory closest to the processor.
