So I was the turtle.

One of the guys I worked with had suggested doing thatswapping out the tires on my bike to road bike tires. Did you notice much of an improvement with speed? I was thinking of giving it a try since I can't afford to buy a road bike right now.

The slicks seemed to provide less surface contact with the road (no nubbies) which seemed to make it easier to accelerate and provides a smoother ride.

I road the mountain bike first too. Only I went to a hybrid, because of the road I live on, I need something that will make it down the dirt road with big rocks and such without getting a flat as soon as I start. LOL
I have loved my mountain bike with slicks. I sold it to my stepmother to get her into a better bike than that px special she had without spending a lot of money and now sometimes I wish I had it back. LOL

The knobby tire has much higher rolling resistance. Mtn bike also weighs a lot more. And if you have suspension without the lock out, you burn more energy going up and down on your shock.

The bright side is when you get a road bike you'll be going a lot faster.

Also being a turtle is far better than being called a jack rabbit. Jack rabbit comment is tad derogatory. It means you are tad slow in the head and don't know how to pace.
