With raw power and a superior blending of architectures, iSeries continues to deliver outstanding results in NotesBench audits. iSeries holds the scalability leadership position in IBM Lotus Domino R6Mail and Calendaring, Notes and Domino Mail and Calendaring, and in Domino Web Access (formerly called iNotes Web Access) with the new, more robust R6iNotes workload. In a May 2004 posting with a 2-way server, iSeries also demonstrated excellent scalability and efficiency with smaller systems, delivering the highest number of users per processor. Each of these benchmarks also features sub-second average response time throughout the required test period.
Since its announcement as a Domino platform in 1998, i5/OS has consistently held a leadership position in the NotesBench audit. These outstanding results stem from a combination of highly scalable hardware and the unique i5/OS subsystem implementation of Domino partitioning.
IBM has further demonstrated the value of the i5/OS subsystem architecture for Lotus applications in a "Three-in-One Benchmark" which combines collaboration workloads (Domino Web Access and Sametime) with line-of-business applications (PeopleSoft World) and a dynamic Web application called Trader3.

Following is a summary of the most recent iSeries and eServer i5 Domino scalability and performance postings:
