Why does breaking wood blocks have such a delay in minecraft, and how do I fix?

Solution 1:

This is a common problem and some fixes work while others don't.

Edit: This may be fixed by deleting your .minecraft map (I suggest you make a back-up first so you can copy/paste your worlds back) and then restarting Minecraft via the launcher to re-download everything.

I also found this to be helpful.

The speed of your Minecraft depends on your FPS, I suggest improving this for faster gameplay. Here is some tips on how to do this.

I would also suggest using a lag-reducing tool like OptiFine. This would allow your game to run smoother and hopefully solve the block delay.
