Few facts:
  • - 8 KB is the default page size on Solaris 10 and 11 as of this writing
  • - both hardware and software must have support for 2 GB large pages
  • - SPARC T4 hardware is capable of supporting 2 GB pages
  • - Solaris 11 kernel has in-built support for 2 GB pages
  • - Solaris 10 has no default support for 2 GB pages
  • - Memory intensive 64-bit applications may benefit the most from using 2 GB pages
Prerequisites:

  2. Add the following line to /etc/system and reboot
    • set max_uheap_lpsize=0x80000000
  3. Finally check the output of the following command when the system is back online
    • pagesize -a
    eg.,
    % pagesize -a
