Node Interleaving
Use this option to enable or disable NUMA node interleaving. Typically, you can obtain optimum performance
on NUMA nodes by leaving this option disabled. When this option is enabled, memory addresses are
interleaved across the memory installed for each processor and some workloads might experience improved
performance.

Enabling or disabling node interleaving

Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Performance Options > Advanced Performance Tuning Options > Node Interleaving and
press Enter.
2. Select a setting and press Enter.
a. Enabled—Memory addresses are interleaved across the memory installed for each processor. All
nodes must be of equal memory size. System performance might be impacted.
b. Disabled—Disables node interleaving, providing optimum performance in most environments.
3. Press F10.
