+ help
+ This lets you select the page size of the kernel. For best
+ performance on memory-intensive applications, a page size of 64KB
+ is recommended. For workloads involving many small files, many
+ connections, etc., it may be better to select 16KB, which uses
+ memory more efficiently at some cost in TLB performance.
+
+ Note that this option is TILE-Gx specific; currently
+ TILEPro page size is set by rebuilding the hypervisor.
