[back to "Optimizing server performance: Domino clusters (Part 1)"]

Multiple Cluster Replicator test results (sidebar)
The following sections show our test results for the CPU and disk utilization for 100 "medium-type" mail users.

CPU utilization
The following table shows the percentage of CPU utilization for 100 "medium-type" mail users on the active server in the clustered configurations. The table also shows the percentage difference in CPU utilization when increasing the number of Cluster Replicator tasks.

Cluster configuration
One replicator task
(N=1)
N replicator tasks
(N=# of standby servers)
Difference in utilization (%)
3-way replication
(1 active and 2 standby)
23.43
19.98
14.72 (-)%
5-way replication
(1 active and 4 standby)
37.08
41.02
10.62 (+)%
6-way replication
(1 active and 5 standby)
42.69
43.13
1.03 (+)%

The following table shows the percentage of CPU utilization for 100 "medium-type" mail users on the standby server in the clustered configurations. The table again shows the percentage difference in CPU utilization when increasing the number of Cluster Replicator tasks.

Disk utilization
The following table shows the percentage of disk utilization for 100 "medium-type" mail users on the active server in the clustered configurations. The table also shows the percentage difference in disk utilization when increasing the number of Cluster Replicator tasks.

Cluster configuration
