POWER supports both 4KiB and 64KiB page sizes; this is in contrast to x86, which supports only 4KiB.
Performance
64KiB mode yields performance improvements for some workloads, if sufficient RAM is available. However, 64KiB mode also incurs higher RAM usage, so users with limited RAM will see better performance in 4KiB mode.
