Amongst other improvements, the latest Safari beta does seem to incorporate the speed optimizations found in the latest Webkit builds. Webkit is an open source project that serves as the basis for Apple's Safari browser. Webkit's nightly builds offer end-users access to the latest (potentially unstable) Webkit updates. A number of other browsers also use Webkit and will also benefit from these improvements.
