FreeBSD 6.0 is the next step in delivering the high performance and enterprise features that have been under development in the FreeBSD 5.x series for that last several years.

Some of the many changes since 5.4 include:

Significant performance improvements to the filesystem and direct disk access layers of the OS. The filesystem is now multithreaded and can take full advantage of multiple CPU systems. Expanded support for wireless networking adapters and new support for the WPA wireless security protocol.
