    he's basically right; the gain you get by disabling the generic things a
    distribution enabled is way down in the noise. There are some
    compromises a distribution makes to keep the number of kernels they ship
    down, and I suspect the worst possible case would add up to say 5%.
    
    (on a Fedora / RHEL that would probably be a SMP system with less than
    1Gb of ram)
    
    On the plus side you get the maintenance, building and integration done
    for you, including the security fixes. 
    
    There is a third "advantage" in using a distro kernel; there is less
    chance of a mistake in the sense of picking a config option that turns
    out to be really bad in hindsight. 
    
    Now that doesn't mean that I want to discourage people from building
    their own kernel, far from that, but at the same time, the advantages
    you get shouldn't be overstated and in a business environment it is
    probably not a good use of time nowadays.
