7### 2.5.x Development news, 08-Feb-2010!
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
11anonymous memory). When used with a SSD (Solid State Drive) swapcache has an enormous positive
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 27## What is DragonFly BSD?
b45421dc 28
29DragonFly belongs to the same class of operating system as BSD and Linux
30and is based on the same UNIX ideals and APIs. DragonFly gives the BSD
31base an opportunity to grow in an entirely different direction from the one
32taken in the FreeBSD, NetBSD, and OpenBSD series.
ab47c073 34The DragonFly project's
b45421dc 35ultimate goal is to provide native clustering support in the kernel.
36This involves the creation of a sophisticated cache management
37framework for filesystem namespaces, file spaces, and VM spaces, which
38allows heavily interactive programs to run across multiple machines with
39cache coherency fully guaranteed in all respects. This also involves being
40able to chop up resources, including the cpu by way of a controlled VM
41context, for safe assignment to unsecured third-party clusters over the
42internet (though the security of such clusters itself might be in doubt,
43the first and most important thing is for systems donating resources to not
44be made vulnerable through their donation).
