Smaller than 1.5 is faster. Recently i tried my mother's bike equipped with Panaracer T Serv 26x1.25 and it is much faster than mine with 26x1.5.

0.9" Conti GP 4000s pumped up to 100psi if they make em in 26 and your rims are not too wide.

perhaps you can consider changing your chainwheel to a larger one? my MTB came with a 42-32-22t chainrings, and i will be converting it to 48-46-36t pretty soon. i already changed my tyres to semi-slick types, which helped to improve the speed marginally.

Used to have 1.75" slicks (1.75" claimed width, actual width closer to 1.6") on my MTB and it was quick to accelerate and felt lighter but top speed wasn't so good. Reason being the skinnier tire makes your overall wheel circumference less, which means you cover a bit less ground with each complete wheel revolution. But if you aren't concerned with top speed, then slicks would be great.

Personally, my bike was at its quickest with Vredestein Black Panther tires. The centre knobs are pretty much continuous so on the straights and at 40 PSI they're like slicks. But they're full-sized 2.0" MTB tires (as in claimed width and actual width is 2.0") so my bike was like freaking fast... they're also very light at about 450g per tire... can't remember exact weight though. Won't be going back to normal slicks anymore.

Currently using Continental X King 2.2". Have used Schwalbe Racing Ralph 2.4" (actual width 2.3") before. Both are fast tires as knobbies go but not in slick tire territory.

Try the Sheldon Gear Calculator. Put in the parameters for your bike, and select KPH @ 60RPM as this is an slightly above average speed which most cyclists are able to ride at. Then change the chain ring sides to 48-36-26t and see the difference in speed.
