The number of fixed-size tables in the kernel has been reduced in each release of the Solaris software environment. Most are now dynamically sized or are linked to the maxusers calculation. Extra tuning to increase the DNLC and inode caches is required for the Solaris 2.4 through Solaris 7 software environments. For Solaris version 2.4 you must tune the pager. Tuning the pager is not necessary for Solaris 2.5, 2.5.1, 2.6, or 7 operating environments.
