what is SuperPagePool"?

[zhi wang_1]

I have 7 HP rx4640, all running HP-UX 11.23 with 4GB memory. However, one of them consumes too much RAM (about 1.6GB) for system mem. Kmeminfo shows two prime suspects of "voilaters".

SuperPagePool = 177571 693.6m 17% Kernel superpage cache
ALLOCB_MBLK_DA = 80401 314.1m 8%

What is SuperPagePool? How can we tune it down?

I searched this forum but have not found any thing helpful.
