Here are some tuning options you should consider implementing on your NIM Server. Generally, most NIM servers are probably fairly small with may be one or two vCPUs and perhaps 8GB of RAM. Make to most of the resources you have.

We recently ran some load testing using Load Runner and the same workload was applied to two different LPARs with the exact same configuration. These tests show the reduced core requirements for a real world p7 to p8 migration.
We recently ran some load testing using Load Runner and the same workload was applied to four different LPARs with the exact same configuration. These tests highlight the negative effects from having high vCPU counts and low Entitlments.
AIX or VIOS Errors: 29FA8C20 and 7BFEEA1F - Adapter ports not connected to the SAN Switch.
AIX and VIO Server testing results for network bandwidth on an E880 for the internal vSwitch and external 1Gbit and 10Gbit switches. Tests include LPAR network bandwidth for core to core, chip to chip and node to node configurations.
