Nope. In fact, you don't really want to know how to configure swap with lots of physical RAM; you want to know how to configure swap for the application mix (which you forgot to tell us about) you're going to run on a box with lots of RAM. Failing that, two guidelines: If you may need to capture kernel core images of panics, you need two times the amount of RAM to get a core image. If you don't care about core images, and expect to never run out of swap, then the system will work fine with no swap files. However, running out of virtual is a rare edge condition and not well tested, so it might behoove you to allocate some so you'll notice it's swapping when you run out, rather than having programs start to fail because you're out of virtual. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
