The cooktop is electric. Btu's has never been an issue before.
The element in question is roughly 9" across, and the stockpot fits it
well, maybe an inch wider.
I filled it up about halfway with water, and sprinkled maybe two or
three tablespoons of kosher salt in there.

Tried it again tonite and let it go a little longer. It didn't have a
problem getting to a strong rolling boil with the lid on. But with the
lid off it went to the large bubbles/strong current breaking the
surface.
It helped when the spaghetti went in. Then it got kind of a strong boil,
but not like with the old pot.
