2da41004 9Our new swapcache is now fully operational in the development branch. Swapcache is a general system
10feature which expands the use of swap to cover clean filesystem data and meta-data (not just dirty
b631bd1b 11anonymous memory). When used with a SSD (Solid State Drive) swapcache has an enormously positive
2da41004 12effect on system performance, almost acting like extended memory. Even a small 40G SSD can cache
13upwards of 80 million inodes for fast directory operations, or make your working dataset completely
14free of slow HD seeks virtually without having to lift a finger. The implications are staggering.

6e5b2f57 28## What is DragonFly BSD?
b45421dc 29
30DragonFly belongs to the same class of operating system as BSD and Linux
31and is based on the same UNIX ideals and APIs. DragonFly gives the BSD
32base an opportunity to grow in an entirely different direction from the one
33taken in the FreeBSD, NetBSD, and OpenBSD series.

ab47c073 35The DragonFly project's
b45421dc 36ultimate goal is to provide native clustering support in the kernel.
37This involves the creation of a sophisticated cache management
38framework for filesystem namespaces, file spaces, and VM spaces, which
39allows heavily interactive programs to run across multiple machines with
40cache coherency fully guaranteed in all respects. This also involves being
41able to chop up resources, including the cpu by way of a controlled VM
42context, for safe assignment to unsecured third-party clusters over the
43internet (though the security of such clusters itself might be in doubt,
44the first and most important thing is for systems donating resources to not
45be made vulnerable through their donation).
