Tuning
Use this information to improve IBM® Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
- Resource balancing and activity trends
  Domino® server resource utilization can be separated into two types, system activity and user activity. System activity, which includes the level of processor, disk, memory, and network consumption that Domino generates to keep the server running, is a fixed amount of activity, as long as systems are healthy and performing smoothly. Domino servers typically use a modest percentage of their resources to run. The remaining server capacity is used to support user activity, which varies with the usefulness of the data on the server.
- The Server.Load tool
  Server.Load is a capacity-planning tool that you use to run tests, also called "scripts" and "workloads," against a targeted Domino® server to measure server capacity and response metrics.
  - Server.Load agents
    Server.Load includes a set of agents in the file NAMAGENT.NSF, which is initially installed in the data directory on the Domino® Administrator client. The first agent in this list -- Create NotesBench Mail Person Documents -- is used to set up Person documents for the workloads and set the HTTP password. The rest of the agents are used to repair and change the workload setup.
  - Server.Load metrics and messaging statistics
    As you run a test, you can view various script metrics and server statistic metrics and optionally store the test output in a separate file. Server statistic metrics are generated by the Domino® server. Script metrics correspond to Server.Load command names and display the performance of particular commands. For example, if you select the Add metric, the Metrics window displays the results of the Add command.
  - Setting up clients and servers for Server.Load
    To use Server.Load, install the Domino® server on the server under test (SUT) and install the Domino Administration client and the Server Load Utility on each client.
  - Built-in and custom Server.Load scripts
    Server.Load includes a set of built-in scripts. You can also create a custom script from scratch.
  - Running the built-in Server.Load workloads
    Server.Load contains numerous built-in workloads and initialization workloads.
