Is it just me... or is Lightroom 4 slower than frozen mud?

Just a little afternoon rant.........

So I've been spending a lot of time on LR4 and it is to the point where I think I will uninstall it and go back to LR3. I like the new tools in the development module, but I have to wait for every minor adjustment I make in the develop module.

So is it me..... is my computer hammered......

I feel better now..... thanks for listening

LR4 converted to stand development. You now have to wait 2 hours with no agitation for your changes to develop.
