I had a look at some parts of http://rlandmann.fedorapeople.org/Installation Guide/en-US/html "7.22.4. SMP Motherboards and GRUB In previous versions of Fedora there were two different kernel versions, a uniprocessor version and an SMP version. In Fedora 11 the kernel is SMP-enabled by default and will take advantage of multiple core, hyperthreading, and multiple CPU capabilities when they are present. This same kernel can run on single CPUs with a single core and no hyperthreading. " This is being repeated since FC-4-6? "Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and then an additional 1x physical RAM for any amount above 2 GB, but never less than 32 MB. So, if: M = Amount of RAM in GB, and S = Amount of swap in GB, then If M < 2 S = M *2 Else S = M + 2" Using this formula, a system with 2 GB of physical RAM would have 4 GB of swap, while one with 3 GB of physical RAM would have 5 GB of swap. Creating a large swap space partition can be especially helpful if you plan to upgrade your RAM at a later time. For systems with really large amounts of RAM (more than 32 GB) you can likely get away with a smaller swap partition (around 1x, or less, of physical RAM)." The formula is not correct. Or is this the result of some special study? I think, S= min{3, 2*M} is best for most desktop users For most servers it should be around Max(5, M/5). Sys admins should determine the actual requirement for servers and scientific computing. There are some recommendations here: http://www.linux.com/feature/121916 Best A. Mani -- A. Mani Member, Cal.
