Sun T5440 SPECjbb2005 Beats IBM POWER6 Chip-to-Chip
By Brad on Jul 20, 2009
- One Sun SPARC Enterprise T5440 (four 1.6GHz UltraSPARC T2 Plus chips, 4RU) demonstrated 5% better performance than the IBM Power 570 (16RU) result of 798752 SPECjbb2005 bops using eight 4.7 GHz POWER6 chips. The IBM system requires twice the number of processor chips and the system requires 4 times more space than the T5440.
- One Sun SPARC Enterprise T5440 (four 1.6GHz UltraSPARC T2 Plus chips, 4RU) has 2.3 times better power/performance than the IBM Power 570 (16RU) that used eight 4.7 GHz POWER6 chips.
- Sun's 1.6GHz UltraSPARC T2 Plus Processor is over 2.3x performance of 4.7 GHz IBM POWER6 processor.
- One Sun SPARC Enterprise T5440 (four 1.6GHz UltraSPARC T2 Plus chips) demonstrated 21% better performance when compared to the Sun SPARC Enterprise T5440 result of 692736 SPECjbb2005 bops using four 1.4GHz UltraSPARC T2 Plus chips.
- The Sun SPARC Enterprise T5440 used OpenSolaris 2009.06 and the Sun JDK 1.6.0_14 Performance Release to obtain this result.

Results and Configuration SummaryHardware Configuration:
Sun SPARC Enterprise T5440
4 x 1.6 GHz UltraSPARC T2 Plus processors
Java HotSpot(TM) 32-Bit Server, Version 1.6.0_14 Performance Release
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
- Enhancements to the JVM had a major impact on performance.
- Each JVM executed in the FX scheduling class to improve performance by reducing the frequency of context switches.
- Each JVM bound to a separate processor containing 1 core to reduce memory access latency using the physical memory closest to the processor.
