FreeBSD 7.2 released, now with Superpages
The FreeBSD developers have completed and released version 7.2 of their free Unix derivative. FreeBSD 7.2 mainly enhances existing functionality and fixes bugs from previous versions of the stable 7.x series and includes some security fixes.
A few new features are added though; The storage system now supports transparent use of "super pages" which increases the paging size for virtual memory from 4KB to 4MB. Application's memory pages will be automatically promoted between normal and "super pages" and offers better virtual memory efficiency. The kernel's addressable virtual memory space has also increased to 6GB to allow subsystems to use more memory; the developers give an example of zfs's adaptive replacement cache as a subsystem which will benefit from the extra address space. Other changes include updates to the boot loader and support for the UltraSPARC III processor family.
Information on the changes and bugfixes in FreeBSD 7.2 can be found in the detailed release notes. The release is available for x86 and x64 processors and IA64, PC98, PowerPC and SPARC64 platforms. The release is available to download as ISO images for CDs and DVDs and is also available using BitTorrent through the FreeBSD Torrent Tracker.
