Real world, I’d be considering this for a Web server. They are a minimum/bare
install with LAMP (e.g. no GUI). A fairly standard page display is 100 - 200
total requests spanning multiple seconds. So I guess I’m wondering if this
would shave a bit off each request (though faster talking with
NIC/disk/etc.)? Anno domini 2019 Thu, 26 Dec 15:08:41 -0500

That is highly dependant on the kernel. At the present time, the version
I built is about 25 fps faster than the raspbian kernel it replaces.
And even that is an older build. On Thursday 26 December 2019 10:30:39 Michael

If you install the kernel src debs, you can do a make menuconfig,
which will allow you access to the kernels fine tuning, and one of
the option buried in the menu's is to turn on a config option call
preempt-rt or preempt-realtime. This changes the IRQ handling to
make the IRQ's be handled much quicker at the expense of making
other stuff wait a few microseconds.
One should also mention, that for a normal user a realtime kernel is a
bad idea, the GUI will not perform better.
