With rather recent kernels, huge pages are used automatically for "normal" memory. There's a background thread that tries to locate or create adjacent blocks of memory and create huge pages from these. But the normal page size as a unit of allocation is still 4KB, and this will never change (with the current hardware). The page size of 4KB is hard-wired into the architecture, and I'm not aware of any extension that allows to change that. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
