I'll quote a slightly-less-technical explanation from Robert L.
Wolke:

As any chemist is happy to calculate for you, adding a
tablespoon (20 grams) of table salt to five quarts of boiling
water for cooking a pound of pasta will raise the boiling
point by seven hundredths of 1(deg)F. That might shorten the
cooking time by half a second or so.
- "Fasta Pasta", /What Einstein Told His Cook/ (W.W. Norton,
2002), ISBN 0-393-01183-6, p. 47.

I'm happy to accept those figures. They reinforce the point that
there's no point in adding salt to speed up the cooking.

Probably I should have written "possibly" instead of "probably"
(possibly). On the basis of unchecked web data, sea water with 35g
dissolved salt per litre boils at about 100.6 deg C, and Dead Sea
water at about 105 deg C. I wouldn't care to cook my pasta in the
latter. The time saved in cooking would be lost in rinsing.

Perhaps I missed it, but have you boffins accounted for the longer time
required to bring a more highly concentrated solution of salt to boiling
point?

Sounds simple - if the solution boils at a higher temp than the pure
water, it needs more energy input; given a fixed heat source it will
take longer to receive this and therefore to boil.
