Activating 2gig pages on Solaris 10.

Giri Mandalika wrote an article how to use the 2 gigabyte page size offered by T4 systems on Solaris 10: “Enabling 2 GB Large Pages on Solaris 10”. This can be really useful if you have an application allocating really large amounts of memory. The more memory a single page covers, the smaller the the translation tables from virtual to physical memory gets, the higher the hit rate of the translation lookaside buffer. However check out your application if it behaves well with such large pages.
