If you are not running a dedicated build machine, it is well worth using a dedicated disk for the poky tmp dir; assuming you have cpu time left, this leaves the machine completely usable for other things.

My experience does not bear this out at all; building Yocto on a 6 core hyper threaded desktop machine I have never ever seen the system memory use to get significantly over a 2GB mark (out of 8GB available), doing Yocto build using 10 cores/threads. On a custom desktop machine with i7-x990 3.47GHz, 8GB ram, quiet conventional hard disks, letting poky use 10 cores/threads (so I can get my work done while it does its own thing in the background), a fresh build of core-image-minimal for beagleboard, with debug & profile tools and test apps, takes 77 minutes. Obviously, not anywhere near as fast as the Intel OTC Xenon beast, but much cheaper HW, and for my purposes the build speed is well in a region where it is no longer a productivity issue.
