Physical machines CPU and paging utilization

In general, machines should be provisioned within the cluster to utilize 10-20% of the central processing unit (CPU) under load. This is to ensure that under heavy load scenarios, failure, and failover cases the remaining cluster members can handle the load. In addition, this reduces the need for the operating system to use virtual memory paging. For on demand solutions, high throughput capable systems that need to handle critical workloads, avoid paging.

In addition, be mindful that many factors affect performance. The following sections are ideas and reminders that programmers and administrators should consider when implementing a high throughput solution, several outside the scope of the partitioning facility itself.
