Paul, Thanks for the clarification. As it so happens my machine has hyperthreading. -----Original Message----- From: fedora-list-bounces@xxxxxxxxxx [mailto:fedora-list-bounces@xxxxxxxxxx] On Behalf Of Paul Howarth Sent: 06 May 2005 09:41 AM To: For users of Fedora Core releases Subject: Re: Linux vmlinuz images On Fri, 2005-05-06 at 08:11 +0200, Denham Eva wrote: > Hello, > > I have done what I would call a standard install of FC3, the only real > mentionable change has been an increase in memory from 512 to 1GB. > My question is this when GRUB starts up and I press enter key for boot > choices.

The "smp" kernel is installed on systems with multiple CPUs. Some recent CPUs with hyperthreading are treated as multiple CPUs and will get the smp kernel installed. Whether or not the smp kernel will result in better performance for you probably depends on the types of applications you are using your system for. Try out both kernels for a while and see if you notice one being faster than the other.
