Tivoli Provisioning Manager 5.1.1.1: 64 Bit System z10 Benchmark Results (801KB)
This document provides results for the IBM Tivoli Provisioning Manager (TPM) 5.1.1 for Linux on System z 64 bit on IBM System z10 benchmark. The benchmark sets new records for TPM, both for overall throughput and concurrency. For example, the benchmark shows that using TPM 5.1.1. for Linux 64 bit on IBM System z10 permits superior performance while using half the number of processors versus prior 31 bit benchmarks on IBM System z990. |

WebSphere on IBM System z 64-bit/31-bit studies with J2EE workloads (1.22MB)
This paper explores a WebSphere Application Server 6.1 system under a customer-like J2EE application workload. The difference in performance behavior of the 31-bit and the 64-bit WebSphere versions was compared, and the impact of heap size and garbage collection was analyzed. The results show a very linear CPU scaling and that with a special scenario at the highest workload level, which utilized eight CPUs, the 64-bit WebSphere version with a large heap showed its strength. |

Performance of an Oracle 10g R2 Database Import Environment (110KB)
The paper describes a specific customer setup of importing data into an Oracle 10g R2 database, comparing the performance on a System z9 and a System z10. The results show an improvement of a factor of two, which is based on the compute intensive workload which was neither burdened by heavy network load nor by the storage server which handled the data rates of up to 250 MB/sec easily. The results confirm that an IBM System z10 can significantly enhances the capabilities of enterprise IT customers. |

Tuning WebSphere Application Server Cluster with Caching (1.03MB)
This paper analyzes parameter and configuration variations in a WebSphere Application Server cluster running the Trade workload when caching is enabled. A secure environment with a DMZ was used to protect the application servers against an uncontrolled external zone. Major findings: System z10 obtained a significant throughput advantage, and z/VM is highly recommended for environments like this. |
