Hitbox Bug: https://bugs.mojang.com/browse/MC-73302
With a smite V sword, strength II and critical hits you need around 3 to 4 seconds to kill a wither.
In Minecraft 1.9 or later versions it might be a little slower due to the attack cooldown.
Instead of the locations listed here you can search one on your own or just use the portal through which you can leave the end.
A few locations with a 3x3 bedrock field:
X:0, Z:-31 (Used in the video.)
X:-56, Z:-67
X:-96, Z:80
X:11, Z:124
X:-154, Z:102
X:-154, Z:-130
A few more good locations can be found in this text file:
