Yes. Don't denormalize the tables.

I would believe performance would be better it being denormalised. (in
this case)

I assume you've arrived at the conclusion because you have (a) shown that the performance with a normalized schema does not meet your needs; (b) benchmarked the normalized schema under production conditions; (c) benchmarked the denormalized schema under production conditions; and (d) shown that performance is improved in the denormalized case to arrive at that conclusion. I'm interested to see the results of your comparisons.

Regardless, it sounds like you've already made up your mind. Why ask for comments?
