[Marvel] Why is Thor's combat speed so slow?

Thor can throw Mjolnir faster than light, he can travel faster than light, he can see and even catch Hermes, the god of speed, when other people can't even detect him because he moves so fast, and so on and so on. But when he's actually fighting, his combat speed is lower than Wolverine or Captain America. How is it that someone with thousands of years of fighting experience and the ability to travel faster than light can't combine those two abilities?

You're addressing lots of different elements there.

Mjolnir is a reservoir of power that gives Thor a great many abilities that alone he would not have. Thor can throw Mjolnir at light speed because of Mjolnir, not his personal abilities.

When he travels faster than light, he is propelling himself bodily, not using his superior reflexes or actual leg speed to do this like hyper-speedsters do. He is using magical power, which only applies to propelling his entire body, not combat reflexes.

Another example is his perception. He can see things that travel extremely fast, it bears no effect on his ability to do anything about it. You yourself can detect events that occur faster than your reflexes can react.

Thor, without his Belt of Strength, Mjolnir and other accoutrements, is really just a very well-bred experienced Asgardian warrior with a very heavy frame. His reflexes are excellent, but he still has a lot of mass to move around in combat, and that slows him down compared to warriors with razor reflexes like Wolverine. 

In fact, a lot of Thor's fights involve getting the crap knocked out of him. It's almost as if part of his fighting style is to absorb damage he knows isn't crippling in order to set himself up for the devastating blows he wants to land. He is known for being a skilled warrior, as in he knows many ways to strike and do damage, but not for his grace in battle.
