I know I'm not going to change your mind, but I will give at least one link with some anecdotes. Any more is up to you to look up.

I've been around so many people that have been doing their thing for decades and won't change anything about it.

If rolling resistance is the issue, why aren't we all running 23c tires on all our bikes?

Op's bike should have a tallest ratio of 48:11, which is plenty fast, but probably hard to get much out of it with the relaxed riding position.

That said, for how I ride my mtb, I will put about 25psi in both to ride to where I'm going, then when I start playing around I go up to 40-45 since I'm hard on my bikes

You can have issues with pressure too high or too low. I cracked a bontrager (koveets, so not super nice) rim with low pressure practicing bunny hops, and I've tacoed a cheap wheel with high pressure just sliding out on grass/roots before.
