Are you using enchanted tools? There was a bug at release where the Efficiency enchantment wasn't working. They fixed it, so everything should be at it's proper mining speed.
The timing is not even close... Certain blocks are instantly destroyed now... It can be very dangerous to mine now if your not careful since dirt,sand,gravel and nether block all destroy instantly... I have even went back to using strictly diamond shovels with no enchantment since they destroy blocks so fast...
I am taking advantage of it now before it gets fixed... I can mine a 3 height level room 50x50 in about 5-10 min now... Perfect time to build that slime farm...lol
I think the "after the patch speed" that we have now is the normal speed. My understanding is that it was designed to be faster to beef up enchantments. If your mining is to fast then build out of obsidian. LOL. That will slow it up.

For instance, you can dig about 50 blocks of sand in about a a second and a half. Sandstone and netherrack are the same.
a lot faster than it used to
