I just thought that if there is a long distance from your hot water
heater or boiler coil to the kitchen maybe a smaller diameter pipe would
get the hot water there faster. Maybe 1/4" or 3/16" tubing would be
better. I may try this.

Simple job, assist the assistant of the physicist.

As long as your water pressure is good it will work. However, long
pipe runs waste heat and water. You lose the heat from the water in
the pipe when you shut off. You lose the water when you run off the
cold water until the hot comes. The solution is to heat the water
not
centrally but locally next to where you want it. This why it's
stupid
in most cases having the water heater in the basement. Far from the
points of use.
Not enough attention is paid to layout in many buildings. Hot water
using equipment needs to be grouped around the source of hot water.

The alternative and wasteful way is to have a circulating pump and
circulate DHW in a similar way to heating systems. This is often done
in very large buildings
