Performance Results The benchmark was conducted using Microsoft's Load Simulator tool. For each test, the Load Simulator Medium MAPI canonical profile was chosen. The Medium MAPI profile reflects the task workload of a typical corporate e-mail user, including common daily mail tasks such as send, browse, read, and forward, as well as calendaring tasks and distribution list usage. The Response Time score represents a 95th-percentile score of the measured test run. The score is expressed in milliseconds (ms). The ProLiant 1600 Response Time score of 230 ms is well below the 1000 ms acceptable threshold for e-mail users utilizing Exchange Server's MAPI protocol. Microsoft has certified these benchmark results based on the Microsoft Exchange Server 5.5 UPS (Users Per Server) Policy Guidelines V1.0. Table 1.

Performance Results
The benchmark was conducted using Microsoft’s Load Simulator tool. For each test, the Load
Simulator Medium MAPI canonical profile was chosen. The Medium MAPI profile reflects the
task workload of a typical corporate e-mail user, including common daily mail tasks such as send,
browse, read, and forward, as well as calendaring tasks and distribution list usage. The Response
Time score represents a 95th-percentile score of the measured test run. The score is expressed in
milliseconds (ms). The ProLiant 1600 Response Time score of 230 ms is well below the 1000 ms
acceptable threshold for e-mail users utilizing Exchange Server’s MAPI protocol. Microsoft has
certified these benchmark results based on the Microsoft Exchange Server 5.5 UPS (Users Per
Server) Policy Guidelines V1.0.
