+1 Depends on the stove, depends on the pot. If the pot is wider than your glass-top burner area, it's not going to heat efficiently no matter how much insulation you wrap it with.
I tried my first batch with a 21-quart enamel canning pot on my glass-top stove, and I couldn't even bring about 3 gallons to a real boil. The pot was wider than the burner area (but not wide enough to go over 2 burners), and it also had a raised center (not helpful!), so the whole brewing session went fairly badly. I bought a Bayou Classic SP-10 propane burner, and started brewing outside, which is great as far as I'm concerned. But if you really want (or need) to be able to brew indoors, then get a pot that fits your burner well and work within its size limitations. Obviously, just in my opinion/experience...
