Obsolete in Solaris 9 and later releases.
The Solaris 8 release changes the way file system pages are cached. These changes subsume the priority paging capability.
Remove both cachefree and priority_paging settings in the /etc/system file.
The caching changes remove most of the pressure on the virtual memory system resulting from file system activity. Several statistics exhibit new behavior:
Page reclaims are higher because pages are now explicitly added to the free list after I/O completes.
Free memory is now higher because the free memory count now includes a large component of the file cache.
Scan rates are drastically reduced.
