cachefree (Solaris 8 Releases)

Obsolete in Solaris 9 and later releases.

Description

The Solaris 8 release changes the way file system pages are cached. These changes subsume the priority paging capability.

---

Note –

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.
