    Sorry, there are no performance gains by removing old kernels. The default on fedora is to keep 3 kernel versions – you can keep more if you wish, or less – it will not change performance. But what it will do, if you don’t have a backup kernel is render your system un-bootable if you don’t keep an old known-to-work version of the kernel.

      Older kernels contaminate the newest one with their slowness and must be removed.
