In early 2005, the Scalability Center for Linux on zSeries (SCL) in Poughkeepsie performed a study on IBM Lotus Domino 6.5 for Linux on IBM System z. During that study, capacity planning and performance data was collected using an industry-standard benchmarking tool to drive both NRPC (Notes) and Domino Web Access (HTTP) e-mail users.
The results of this benchmark showed two bottlenecks that prevented linear scalability of throughput for Domino 6.5 for Linux on System z.
Domino 7.0 and z/VM 5.2, which both became available later in 2005, offer relief for these two bottlenecks.
This IBM Redpaper discusses the results of those tests and provides some recommendations.
