A short summary of some of the changes since last update besides support for the SPARC T4:
- Support for Two-Terabyte Memory Systems You can install Oracle Solaris on systems with more than 2 TB of memory.
- ZFS Enhancements such as ZFS diff, ZIL synchronicity, RADIZ/mirror hybrid allocator and read-only import.
- diskinfo Utility The diskinfo command-line utility enables system administrators to see the relationship between logical disk names (cXtYdZ) and bays in a JBOD or blade chassis.
- Shared Memory Enhancements Changes in creating, locking, unlocking, and destroying Intimate Shared Memory (ISM) and Dynamic Intimate Shared Memory (DISM) have resulted in significant performance improvement in the startup and shutdown of the Oracle database.
- SPARC: Support for Fast Reboot The integration of the Fast Reboot feature of Oracle Solaris on the SPARC platform enables the -f option to be used with the reboot command to accelerate the boot process by skipping certain POST tests.
- libmtmalloc Improvements libmtmalloc has undergone a performance improvement that specially targets 64-bit applications with a large number of threads.
- LDAP Name Service This section summarizes enhancements that have been made to the LDAP name service in this release. LDAP name service stand-alone support – This enhancement enables the LDAP name service tools ldapclient, ldapaddent, and ldaplist to populate and test an LDAP directory without having to configure the name service switch to use LDAP.
- Samba Upgrade to Version 3.5.8
Samba, which provides file and print services to SMB/CIFS (Server Message Block/Common Internet File System) clients, has been upgraded to version 3.5.8.
Update: This release could provide better ZFS performance besides the new features, around 7-20% for reads and 10-15% for writes. The tests where done with a few simple dd(1) instances but interesting anyway, read more here.
