What you end up with is a vendor kernel that has been specifically
tested in a given workload, and they tend to work very well in that
config.  The vanilla kernels do have a broader testing base, and they do
get a wider variety of bug fixes.  But they don't get the concentrated
high end certification and testing the vendor kernels do.  And that last
little bit of certification is _really_ hard.

But not a recent example of someone using them in a high end
configuration.  It's even possible that someone has, but doing it over
time for release after release?  Those are the customers that end up
going to redhat and suse.
